Make CI run automatically and pass

[ElusAegis]

1. CI Improvements:
   Updated CI configuration to automatically trigger on both push and pull_request events, ensuring all commits and PRs are automatically tested.

2. Submodule Configuration Fix:
   Resolved an error in .gitmodules by correcting submodule urls to reference the appropriate repository owners instead of the incorrect lib directory. This ensures proper initialization of submodules. Sample of the original code failing.

3. Solidity Test Fix (testMint Error):
   Fixed a crash in the Solidity test testMint caused by the absence of the test/metadata folder. This adjustment ensures the required directory structure exists, allowing tests to run smoothly.
