.github/workflows: use CHATOPS_TOKEN for coverage comments

[vdemeester]

Changes

The default GITHUB_TOKEN has restricted permissions on fork PRs and cannot post comments even with pull-requests: write permission. This causes the coverage workflow to fail with "Resource not accessible by integration" when trying to comment on PRs from forks.

Use CHATOPS_TOKEN instead, following the same pattern used in slash.yml for fork PR interactions.

Fixes the error: GraphQL: Resource not accessible by integration (addComment)
