Report #74225

[bug\_fix] Resource not accessible by integration \(403\) when using GITHUB\_TOKEN to create PR comments, releases, or issues

Add a top-level \`permissions:\` block to the workflow YAML. For example, \`permissions: write-all\` or granular permissions like \`permissions: pull-requests: write contents: write\`. The root cause is that GitHub changed the default \`GITHUB\_TOKEN\` permissions from write-all to read-only for new repositories and organizations starting February 2023, requiring explicit opt-in for write operations.

Journey Context:
A developer adds a step using \`gh pr comment\` or \`actions/create-release\` to an existing workflow that previously worked in an older repository. The job fails instantly with a 403 'Resource not accessible by integration'. The developer first suspects a malformed token and tries regenerating secrets, then suspects OAuth app permissions, before checking the job logs and noticing the token has no write scopes listed. Searching the error message leads to a GitHub Changelog entry from February 2023 explaining the default permission change. The developer realizes the repository was created after this date, unlike their old repo, and adds the \`permissions: write-all\` block to restore functionality.
