ci: use Python 3.12 in Xcode workflows and exclude Source/Data from Swift/C++ CI

- Upgrade actions/checkout from v4 to v5
- Upgrade actions/setup-python to v6 with Python 3.12
- Upgrade peter-evans/commit-comment from v3 to v4
- Add paths-ignore for Source/Data/** in both workflows
- Fixes Python 3.9 compatibility issues with PEP 604 union syntax
- Prevents triggering Swift/C++ CI when only Source/Data changes

All actions now use latest stable versions with Node 24 runtime.
