This pull request makes a small update to the Renovate configuration for GitHub Actions dependencies. The change expands the exclusion pattern in the matchPackageNames field to also exclude github/** packages, not just actions/**.

• .github/renovate/base.json5: Updated the matchPackageNames pattern to exclude both actions/** and github/** when applying the deps:actions label for GitHub Actions dependencies.

should we also exclude "googleapis/*" - i think it's well-trusted too.

Pull request overview

This PR updates the Renovate configuration to exclude both actions/** and github/** packages from having their GitHub Actions pinned to commit digests. This ensures that first-party GitHub Actions (from both the actions and github namespaces) remain unpinned, while third-party actions continue to be pinned for security purposes.

Key Changes

• Expanded the exclusion pattern in the "Pin 3rd-party actions" rule to include both actions/** and github/** namespaces

Personally, I'm also +1 on excluding it. They're Google-owned actions, so I think that's fine.

But, if the TSC has a moment to review it, another confirmation would be helpful. @eslint/eslint-tsc

LGTM, thanks!

Since eslint/js#712 (comment) and the related PRs for the release-please version pinning have been merged, I'm merging this now to align with them.

If it really matters, I think we can start to discuss it in a separate issue :)
