Replace json-schema-to-typescript: not maintained and too many dependencies

[thernstig]

json-schema-to-typescript is hardly maintained anymore, see https://github.com/bcherny/json-schema-to-typescript and the commit history.

What is worse its dependencies look like this:

    "node_modules/json-schema-to-typescript": {
      "version": "15.0.3",
      "resolved": "https://registry.npmjs.org/json-schema-to-typescript/-/json-schema-to-typescript-15.0.3.tgz",
      "integrity": "sha512-iOKdzTUWEVM4nlxpFudFsWyUiu/Jakkga4OZPEt7CGoSEsAsUgdOZqR6pcgx2STBek9Gm4hcarJpXSzIvZ/hKA==",
      "license": "MIT",
      "dependencies": {
        "@apidevtools/json-schema-ref-parser": "^11.5.5",
        "@types/json-schema": "^7.0.15",
        "@types/lodash": "^4.17.7",
        "is-glob": "^4.0.3",
        "js-yaml": "^4.1.0",
        "lodash": "^4.17.21",
        "minimist": "^1.2.8",
        "prettier": "^3.2.5",
        "tinyglobby": "^0.2.9"
      },
      "bin": {
        "json2ts": "dist/src/cli.js"
      },
      "engines": {
        "node": ">=16.0.0"
      }
    },

Notice hhow it uses e.g. prettier which is in reality a dev tool, and lodash in 2026 is arguably bad. There should be better options.

One is https://www.npmjs.com/package/json-schema-to-typescript-lite. There are others.

Replacing it would reduce payload's bundle size. I think Payload should take more care into looking into its dependencies to scale down to minimalisticc versions and remove some deps altogether.
