Verify no actions/stale permissions needed (no stale workflows present)

[Copilot]

Summary

This PR confirms that no changes are needed to address the issue "Add missing actions/stale permission" because no workflows in this repository currently use actions/stale.

Investigation Results

After a comprehensive search of the repository:

1. No current workflows use actions/stale: Searched all .yml and .yaml files in .github/workflows/ and confirmed no references to actions/stale
2. Historical context: A close-stale-issues.yml workflow was added in PR add automation to close stale issues open-telemetry/opentelemetry-python-contrib#393 (April 2021) that used actions/stale@v3, but this file has since been removed from the repository
3. Upstream verification: Confirmed via GitHub API that the upstream open-telemetry/opentelemetry-python-contrib repository also doesn't have any actions/stale usage

Conclusion

The issue states: "Check if any workflow jobs are using actions/stale. If so, make sure that the permissions block for that job contains actions: write"

Since the conditional requirement ("if any workflow jobs are using actions/stale") is not met, no changes to workflow permissions are necessary. The task is complete with no modifications needed.

If a stale workflow is added in the future, the permissions block should include:

permissions:
  contents: read
  actions: write  # because actions/stale deletes its old cache before saving new one
  issues: write
  pull-requests: write

Closes #[issue-number]

Original prompt

---

This section details on the original issue you should resolve

<issue_title>Add missing actions/stale permission</issue_title>
<issue_description>Check if any workflow jobs are using actions/stale.

If so, make sure that the permissions block for that job contains

actions: write

If any of the other permissions lines have trailing comments, then add a trailing comment for this one too:

actions: write # because actions/stale deletes its old cache before saving new one

Place this new permission in a specific order within the permissions, directly before both:

issues: write
pull-requests: write

(which implicitly means after contents: read)</issue_description>
