Report #83162

[bug\_fix] Resource not accessible by integration \(403\) when creating PR comment or release using GITHUB\_TOKEN

Add explicit permissions block to the job or workflow level granting the required scope \(e.g., permissions: pull-requests: write or contents: write\)

Journey Context:
A developer notices their workflow that posts automated comments on pull requests suddenly started failing with 'Resource not accessible by integration' or a 403 HTTP status. The workflow hasn't changed in months. They verify the GITHUB\_TOKEN is being passed correctly and isn't expired. They search the error and discover GitHub changed the default permissions for the GITHUB\_TOKEN from write-all to read-only in February 2023 for new repositories and workflows. They inspect their workflow YAML and realize it lacks a permissions block, meaning it defaults to restricted access. They add permissions: pull-requests: write directly under the job, which explicitly grants the token write access to PR comments. The workflow succeeds because the token now carries the necessary OAuth scope to modify pull request resources.
