chore(ci): fix CI not triggering on sdk-test-data update

[rasendubi]

Example sdk-test-data update not triggering CI: #237

Note that it triggered Dart SDK checks but not other SDKs. This happens because sdk-test-data is a submodule, so it's treated as a file (not directory) during checking for updates.

This PR removes /** from all sdk-test-data patterns (same as in dart.yml), so it should trigger the rest of checks.
