fix(workflows): improve maintainer detection for automated PR actions

[bdmorgan]

Summary

This PR improves the maintainer detection logic in the .github/workflows/gemini-scheduled-stale-pr-closer.yml and .github/workflows/pr-contribution-guidelines-notifier.yml workflows. It addresses an issue where PRs from maintainers (specifically Googlers or members of other maintainer teams) were being incorrectly identified as community contributions and, in some cases, automatically closed.

Details

• Expanded Team Verification: Added gemini-cli-askmode-approvers and gemini-cli-docs to the list of teams checked for maintainer status in the stale PR closer.
• Googler Verification: Implemented a check for membership in the googlers or google organizations. This ensures that PR authors from the core team are correctly identified as maintainers even if they aren't explicitly in a specific repository-level team.
• Asynchronous Logic: Updated the isMaintainer function in the stale PR closer to be asynchronous and properly handled await across its usage.
• Consistency: Applied similar Googler verification logic to the pr-contribution-guidelines-notifier.yml workflow to prevent sending unnecessary contribution guideline notifications to internal team members.

How to Validate

Since these are GitHub Actions workflows, validation involves observing the workflow execution on GitHub:

1. Trigger the Gemini Scheduled Stale PR Closer workflow manually or via a PR edit.
2. Verify that PRs from members of the newly added teams or Googlers are correctly identified as maintainer PRs in the logs.
3. Verify that these PRs are no longer closed for missing linked issues.
