Merge https://github.com/google/adk-python/pull/5391
## Summary
- Add `if: github.repository == 'google/adk-python'` guard to 3 workflows that lack this protection: v2-sync, issue-monitor, and copybara-pr-handler
- These workflows use secrets unavailable on forks (RELEASE_PAT, ADK_TRIAGE_AGENT, GOOGLE_API_KEY), causing daily failures on forks
## Context
Other scheduled/repo-specific workflows (triage.yml, stale-bot.yml, upload-adk-docs-to-vertex-ai-search.yml) already have this guard. These 3 were missing it, causing errors on forks every day.
## Testing Plan
- Verified that the added condition matches the existing pattern used in triage.yml, stale-bot.yml, and upload-adk-docs-to-vertex-ai-search.yml
- On forks, the job will be skipped (same behavior as the already-protected workflows)
- On google/adk-python, the workflows will continue to run as before since the condition evaluates to true
