Update MOM5 package to use new option to not use git commit hash versioning

[aidanheerdegen]

This PR adds the ability to build MOM5 in ACCESS-OM2 without the git hash versioning

mom-ocean/MOM5#384

Once it is merged to take advantage of that the --no_version option would need to be added here:

https://github.com/ACCESS-NRI/spack_packages/blob/cice5/packages/mom5/package.py#L307-L311

It should probably be made conditional on MOM5 version. Or specify that MOM5 must be that version or greater to build.

PR #51 for --no_version.
It's not conditional at the moment, but we probably need to make all the SPDs conditional on the new tags that have been introduced.
