[bug\_fix] Resource not accessible by integration when creating PR comment using GITHUB\_TOKEN

Explicitly declare the \`permissions\` block in the workflow YAML. Add \`permissions: pull-requests: write contents: read\` at the workflow or job level. This overrides the default restrictive permissions \(read-only for contents, none for PRs\) applied to workflows triggered by fork pull requests.

Journey Context:
A developer configures a workflow to post a comment on a PR with test results using \`actions/github-script\` and \`github.rest.issues.createComment\`. It works perfectly on their own branches, but every external contributor PR fails with "Resource not accessible by integration". The developer checks the repository settings under Actions > General > Workflow permissions and sees "Read repository contents and packages" is selected. They try switching it to "Read and write permissions" but the error persists for fork PRs. After examining the job logs, they notice the GITHUB\_TOKEN has no \`permissions\` block in the YAML. They add \`permissions: pull-requests: write\` to the specific job, realizing that fork PRs run with a read-only token by default unless explicitly granted permissions in the workflow file itself. The fix works immediately because the token now receives the \`write\` scope for PRs.
