Barry Roodt f89c362b26 fix(docs): accept a GitHub token for docs content reads (#48364)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Bug fix. Complete App configurations produce the same auth options as
before.

## What is the current behavior?

Without the docs GitHub App private key, two things fail for a
contributor:

- `pnpm run embeddings` aborts before doing any work. The lint warnings
source throws, and every source shares one `Promise.all` in
[`fetchAllSources()`](https://github.com/supabase/supabase/blob/master/apps/docs/scripts/search/sources/index.ts).
- `pnpm --filter docs build` exits 1 in prebuild, so the `npm run build`
pre-flight CONTRIBUTING.md asks for cannot run either:

```
Error: DOCS_GITHUB_APP_PRIVATE_KEY environment variable is required
    at octokit (apps/docs/lib/octokit.ts:21:13)
    at fetchAiSkills (apps/docs/scripts/federated-content/fetch-federated-content.ts:258:36)
```

Both read public content, so this is a rate-limit guard rather than
access control: App auth landed in #43015 because unauthenticated calls
(60 req/hr per IP) went flaky on shared runners.

## What is the new behavior?

`apps/docs/lib/octokit.auth.ts` adds one rung below the App: a token
from `GH_TOKEN`, then `GITHUB_TOKEN` (the precedence [`gh help
environment`](https://cli.github.com/manual/gh_help_environment)
documents), so `export GH_TOKEN=$(gh auth token)` is enough to build
locally. Still authenticated, so #43015's fix holds, and still an
authenticated Octokit client, so #44274 holds.

A partially configured App is now an error naming the missing vars,
rather than falling through to a token.

Used by the lint warnings loader and `lib/octokit.ts`. The two token
vars are declared in `apps/docs/turbo.jsonc` for
`turbo/no-undeclared-env-vars`.

## Additional context

With only `GH_TOKEN` set, `turbo run build --filter=docs --force` passes
4/4 and search-index source loading completes. `pnpm test` passes (20
files, 164 tests), and `tsc --noEmit` plus `pnpm run lint` match
`origin/master`. For a complete App config the auth options are
identical to before. Happy to post the fuller verification as a comment.

## Summary by CodeRabbit

- **New Features**
- Added flexible GitHub authentication for documentation services,
supporting GitHub App credentials or personal access tokens.
- GitHub App authentication is preferred when fully configured, with
token-based fallback when unavailable.
- Added support for both `GH_TOKEN` and `GITHUB_TOKEN`, with clear
precedence rules.

- **Bug Fixes**
- Improved configuration validation with clear errors for missing or
incomplete authentication settings.
- Standardized authentication across GitHub content and lint-warning
retrieval.
