docs: fix CI-breaking imports, missing code-fence languages, and typos

[claude]

Requested by Archie McKenzie · Slack thread

Summary

Daily automated documentation scan across docs/en-US/, blog/en-US/, devlog/en-US/, and authors/. One subagent audited each subsection against CONTRIBUTING.md; only high-confidence, mechanical fixes were applied.

Before / After (by subsection)

core

• index.mdx: had a bare import Video from '@/components/Video' in the MDX body — a CI hard-fail. Removed the import; <Video> renders fine without it (same pattern already used in docs/en-US/locadex/mintlify.mdx).
• quickstart.mdx: fixed a missing "and" ("...click Create API Key" → "...and click Create API Key") and a duplicated phrase ("check the enqueue the file" → "enqueue the file").
• class/methods/locales/is-same-language.mdx: "Works with variable number of locale parameters" → "Works with a variable number of locale parameters".
• functions/locales/requires-translation.mdx: description was missing mention that it considers "the approved locale list" — restored the dropped clause.
• class/methods/formatting/format-date-time.mdx: removed a dangling, empty "## Next steps" heading with no content under it.

next

• api/config/with-gt-config.mdx: fixed a non-existent function name (withGTProps → withGTConfig), a missing subject ("If a non-supported request is received will reroute..." → "...is received, it will reroute..."), and a stray underscore in a prop name (_batchInterval → batchInterval).
• api/middleware/create-next-middleware.mdx: the example set prefixDefaultLocale: true directly under prose explaining how to set it to false — corrected the example to false to match the text.
• api/strings/get-gt.mdx: "Translations strings with getGT happen..." → "Strings translated with getGT happen...".
• index.mdx: "Both <T>, useGT(), and getGT()" → "All of <T>, useGT(), and getGT()" (both only applies to two items).
• guides/local-tx.mdx: removed a dangling, empty "API References:" bullet at the end of the "Next steps" list.
• tutorials/examples/next-speedrun.mdx: fixed a mismatched "either...and" construction, "Dev Api Keys" → "Dev API Keys", and "General translation" → "General Translation" (product name).
• tutorials/examples/currency-converter/setup.mdx: fixed faulty verb parallelism ("simulate...and displays" → "simulate...and display").

node

• guides/strings.mdx: frontmatter description said "Two approaches" but the page describes three — updated to match.
• api/get-translations.mdx: example CLI command used the wrong binary name (npx gtx translate → npx gt translate).
• api/strings/msg.mdx: "Translations strings with msg happen..." → "Strings translated with msg happen...".

cli

• formats/gt.mdx: page title "GT JSX" didn't match its content or how every other page links to it — retitled to "GT".

locadex

• mintlify.mdx: a "Next.js App router" link pointed at the general Locadex index instead of the dedicated Next.js guide — fixed the link target.
• auto-merge.mdx: image alt text had a misplaced closing quote ("Locadex Agent selected" → "Locadex Agent" selected).

react / react-native

• api/components/gtprovider.mdx (both packages): "Render settings controls..." → "Render settings control..." (subject-verb agreement).

react-core-linter

• index.mdx, guides/quickstart.mdx: removed the same CI-hard-fail import Video statement described above.

next-lint

• index.mdx: "Subject to changes." → "Subject to change." (fixed idiom).

blog

• i18n-without-translation-files.mdx: removed a CI-hard-fail import Video statement.
• multilingual-nextjs-seo.mdx, plurals.mdx: added missing language ids (txt) to 6 fenced code blocks that had none.

devlog

• gt-react_v10_15_0.mdx, gt-react_v10_19_0.mdx, react-core-linter_v0_1_0.mdx: removed CI-hard-fail import Video statements.
• gt-next_v6_3_0.mdx, gt-react_v10_18_0.mdx: added missing language ids (text) to fenced code blocks.

authors

• jackie.mdx: frontmatter was missing the required occupation field — added occupation: Software Engineer (matches the bio text).

How

32 files changed, all under docs/en-US/, blog/en-US/, devlog/en-US/, and authors/. No changes to docs-templates/. Every fix above was verified by reading the actual file content before editing; several lower-confidence findings from the scan (ambiguous wording, unverified SDK parameter names, factual contradictions needing a maintainer's judgment call) were deliberately left unfixed and are not included in this PR.
