Use -X instead of --debug for Maven debug logging

In Maven 3, the `--debug` option enabled verbose debug logging.
However, in Maven 4, it behaves like `mvnDebug`, causing Maven to
pause and wait for a debugger connection.

To ensure consistent behavior across Maven 3 and 4, switch from
`--debug` to `-X`, which retains verbose debug logging in both
versions.
