fix(commitlint): add pull-requests:read permission so wagoid action can fetch PR commits

The wagoid/commitlint-github-action requires `pull-requests: read` to call
GitHub's API for the list of commits on the PR. Without it, the action errors
with `Resource not accessible by integration` and the workflow fails opaquely.

Fleet-propagated by /jc-coding-fleet-driver from the failure pattern observed
on www.Stella-Maris.xyz#23 + Errors.CloudIngenium.com#23.
