ci: re-enable Linux builds with error handling

Re-enable the Linux build matrix with Swift 6.0 and 6.1 on Ubuntu
Noble and Jammy. Added continue-on-error: true to coverage steps
to ensure coverage failures don't fail the build workflow.

Linux build matrix includes:
- Swift 6.0 on Ubuntu Noble/Jammy
- Swift 6.1 on Ubuntu Noble/Jammy
- Coverage processing and upload with error handling
