fix(bundle-jvm): Correct glob example in collision warning

The warning suggested --exclude='**src/debug/**', but in globset '**' is
only a recursive wildcard when it is a whole path segment. Adjacent to
other characters (as in '**src'), it is parsed as '*src' and matches a
single segment, so the hint would not apply in multi-module projects.
Use '**/src/debug/**' instead.
