Add +restart_repro variant for mom5

Closes #53

[github-actions]

The model version in the spack.yaml has not been updated.
Either update it manually, or comment the following to have it updated and committed automatically:

• !bump major for feature releases
• !bump minor for bugfixes

I think I've used the right syntax for this, but happy to be told otherwise.

The other option is that we add this as the default variant for the access-om2 SPD. Don't mind either way, but not sure what that would entail.

!bump major

[github-actions]

✅ Version bumped from 2023.11.23 to 2024.03.0 ✅

[aidanheerdegen]

Bumped the major version because bitwise restart reproducibility represents a significant change in functionality.

We're going to need to push a new spack-packages version to pick up the updated mom5 SPD right @CodeGat?

Edit: and then we'll need to change the version in config:

The Ci is failing because it's not comparing the versions correctly. Haven't dealt with the case as seen here: https://github.com/ACCESS-NRI/ACCESS-OM2/pull/54/files#diff-e8582e74fa156f4e5729a850e52b24f2fde2d815c2c9c360f88c4cf90db851abR13
This will require an update to the CI to fix, but I'll go through the packages.yml syntax. Also with regards to

We're going to need to push a new spack-packages version to pick up the updated mom5 SPD right @CodeGat?

Yes, we will need to. Not only that, we will need to update the version of spack-config in the versions.json as the current one is using spack-start.bash rather than spack-enable.bash @aidanheerdegen

[aidanheerdegen]

No longer required as +restart_repro was made default for mom5
