Subject: [PATCH] fix(java): use stable file locations for JARs provided by
 mason.nvim

Since the introduction of the new registry, packages started linking
more than executables (`bin/`) in Mason's root directory. Examples of
these are platform-agnostic "share" files, for example the JARs used
here.

Reaching into the internal package structures of Mason packages is not
stable and is prone to break across versions.
