Report #16273

[bug\_fix] Resource not accessible by integration when creating PR comments with GITHUB\_TOKEN

Add explicit permissions to the workflow job: \`permissions: pull-requests: write\` \(or \`permissions: write-all\` for broader needs\). Root cause: GitHub changed the default GITHUB\_TOKEN permissions from permissive \(read/write\) to restricted \(read-only for contents\) for new repositories and organizations in February 2023 to improve security posture.

Journey Context:
You configure a workflow that posts a comment to a pull request using \`actions/github-script\` or \`peter-evans/create-or-update-comment\`. The workflow fails with a 403 Forbidden and the message "Resource not accessible by integration". You check the repository Settings > Actions > General and see that Workflow permissions are set to "Read repository contents and packages permissions" \(the default\). You recall this exact workflow working in a personal repository created last year. After searching the error message, you find GitHub's blog post from February 2023 announcing the change to secure defaults. You realize the GITHUB\_TOKEN now lacks \`pull-requests: write\` permission by default. Adding the explicit \`permissions\` block at the job or workflow level immediately resolves the 403 error.
