* feat(ci): exclude deploy/base directory from link checking

Add deploy/base to lychee.toml exclude_path to skip link checking for all files in the deploy/base directory, which contains third-party Helm charts that may have external links that could break over time.

* revert(docs): restore original Grafana README links and keep deploy/base exclusion

Reverted link fixes in Grafana README since deploy/base directory is now excluded from link checking. This maintains third-party Helm chart integrity while preventing future link check failures.
