Subject: [PATCH] Fix actionlint config path resolution after cd into REPO_ROOT

After `cd "$REPO_ROOT"`, the config file checks still referenced
`$REPO_ROOT/.github/actionlint.yml`, creating a double-nested path
(e.g., FuzzyBot/FuzzyBot/.github/actionlint.yml) that never exists.
This caused the script to always fall back to the GitHub-Actions
default config, silently ignoring repo-local actionlint configs.

Use paths relative to cwd (which is already inside the repo after
the cd) instead of prefixing with $REPO_ROOT.
