Fix agentic triage workflow invalid id-token permission

[timotheeguerin]

Problem

The agentic triage workflow fails to run with:

GitHub Actions / .github/workflows/issue-triage.lock.yml Invalid workflow file
(Line: 388, Col: 17): Unexpected value 'read'

This started after #10984 ("Enable org-billed Copilot auth") replaced permissions: read-all with the gh-aw shorthand:

permissions:
  all: read
  copilot-requests: write

The all: read shorthand expands to every permission set to read — including id-token: read, which GitHub Actions rejects (id-token only accepts write or none). Bumping the compiler version alone does not fix this; the all: read source is the culprit.

Fix

Following the pattern used in Azure/azure-sdk-for-js#39089:

• issue-triage.md & bump-tcgc-csharp.md: replace all: read with explicit contents: read + issues: read (keeping copilot-requests: write).
• check-agentic-workflows.yml: bump the pinned gh-aw from v0.79.8 → v0.80.9 so the drift check matches.
• Recompiled with gh aw compile (v0.80.9), regenerating the .lock.yml files, agentics-maintenance.yml, and actions-lock.json.

Verification

• id-token no longer appears in any generated workflow.
• Both lock files parse as valid YAML.
• Agent job permissions are now contents: read, issues: read, copilot-requests: write.
