ci: group dependabot github-actions updates into fewer pull requests

[spydon]

What

Replaces the mostly ungrouped github-actions Dependabot config with four groups:

Group	Pattern	Purpose
codeql-action	github/codeql-action*	Pre-existing. init and analyze must run the same version.
supabase-sdk-workflows	supabase/sdk*	New. Reusable workflows sharing one repository's release tags.
supabase-actions-workflows	supabase/actions*	New. Same, for the three workflows pinned to one commit.
actions-minor-patch	* (minor, patch)	New. Batches every remaining non-breaking bump.

Group order matters: Dependabot assigns each dependency to the first group it matches, so the three specific groups are listed before the catch-all.

Why

Lockstep dependencies were being split. Dependabot treats each reusable workflow as its own dependency, named by its full path. The supabase/sdk v1.1.1 to v1.2.0 bump therefore arrived as two pull requests, #1755 and #1756, and between the two merges the repository had two callers pointing at different releases of the same source. supabase/actions has the same exposure but larger: three reusable workflows in stale.yml, label-issues.yml and block-merge.yml, all pinned to commit 2e898cb, so its first bump would have landed as three separate pull requests.

Volume. Ten individual bump pull requests merged across 2026-08-12 and 2026-08-13, five on each day. The catch-all collapses that into roughly one per week.

Deliberately not grouped

Major bumps match no group and keep arriving as individual pull requests. A bump like the earlier actions/upload-artifact 4.6.2 to 7.0.1 should be reviewed and revertable on its own rather than buried in a batch.

Verification

• .github/dependabot.yml parses, and the four groups resolve in the intended order.
• Confirmed the existing codeql-action group is already working: codeql.yml:41 and codeql.yml:47 are both pinned to ff2f1c62 at v4.37.7. Past bump titles name only analyze because Dependabot titles a group after a single member when only that member moved.
• Audited all 19 uses: references across .github/workflows/. Apart from the three groups above, no remaining action is coupled to another.

Note

Grouping takes effect on the next Dependabot run. Both #1755 and #1756 have since been merged, and supabase/sdk is back in sync at v1.2.0 in both callers, so nothing needs recreating.

Summary by CodeRabbit

• Chores
  • Configured automated updates to group reusable workflow dependencies by repository.
  • Grouped minor and patch updates for GitHub Actions, while keeping major updates separate for review.

📝 Walkthrough

Walkthrough

Dependabot now groups supabase/actions reusable workflows by repository. It also groups minor and patch GitHub Actions updates. Major updates remain separate.

Changes

Dependabot workflow grouping

Layer / File(s)	Summary
Group workflow dependencies .github/dependabot.yml	Groups supabase/actions workflows and other minor or patch GitHub Actions updates. Major updates remain ungrouped.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to a6303

Major dependency updates could be bundled with other changes instead of remaining individually reviewable and revertable, increasing the chance of an insufficiently isolated breaking update. Merge should wait until the group is restricted to minor and patch updates.
