Add minimum permissions to PR label workflows

[Tomlu60220244]

Fixes #8592

What changes did you make?

Added explicit workflow-level permissions to the PR label workflows.

For .github/workflows/set-pr-labels.yaml:

• contents: read
• issues: read

For .github/workflows/wr-set-pr-labels.yaml:

• contents: read
• actions: read
• issues: write
• pull-requests: write

Why did you make the changes?

This limits the default GITHUB_TOKEN permissions to the minimum required access for these workflows, following GitHub Actions security best practices.

pull-requests: write is included only in .github/workflows/wr-set-pr-labels.yaml because testing confirmed that this workflow needs write access to pull requests. It was removed from .github/workflows/set-pr-labels.yaml because that workflow does not write to pull requests.

Testing

Testing confirmed that pull-requests: write is required for .github/workflows/wr-set-pr-labels.yaml, but it is not needed for .github/workflows/set-pr-labels.yaml.

With these permissions, each workflow has the minimum permissions needed for its behavior.

Hey @Tomlu60220244 - Thanks for working on this! We already discussed the reason to add the pull-requests: write permission to wr-set-pr-labels.yaml in #8592. Great catch on this!

The only comments I have are:

• please confirm that the pull-requests: write permission is needed on set-pr-labels.yaml. Since the workflow is not writing to the PR in this step it should not be needed. I tested the workflow in my repo, and unless you are seeing something different from me I don't believe this is needed.
• very minor thing, but please check the Action Item boxes in the original issue.

Great job again!

Thanks @t-will-gillis for checking this.

I’ll remove pull-requests: write from .github/workflows/set-pr-labels.yaml since that workflow does not write to the PR. I’ll keep pull-requests: write in .github/workflows/wr-set-pr-labels.yaml, where it is needed.
