fix: multi-runner-build-workflow release-please excludes (#1572)

fix: scope multi-runner-build-workflow release path to its workflow file

Previously the package tracked the entire .github/workflows directory and
excluded only release-please.yml and zizmor.yaml. As more unrelated
workflows were added (build-*, flux-diff, terragrunt, org-*, shared-*,
test-use-mise) they could trigger spurious version bumps of the
multi-runner-build-workflow component, and the zizmor.yaml exclude
became stale after that file was renamed to shared-zizmor.yml.

Expand the exclude list to cover every workflow file other than
multi-runner-build.yml itself.
