Multi-Supercomputer-Proof Generic Workflows

[CodeGat]

Background

See https://github.com/ACCESS-NRI/build-cd/pull/111/files/a34bb0b53657f169450c8ac31a9c3463c9837567#r1758047493 and https://github.com/ACCESS-NRI/build-cd/pull/111/files/a34bb0b53657f169450c8ac31a9c3463c9837567#r1758181572

We have gone quite far in making this repo able to handle multiple supercomputer targets, but we aren't 100% there yet. Things like comment explicitly referring to Gadi, explicit paths to /g/data/vk83/... in comments, among other things.

Audit this repositories use matrices, comments and targets to make sure we can deploy to another supercomputer target as easily as possible.

One main issue is the GitHub Release - matrixing could lead to multiple releases of the same version of a model, with different spack.locks for different targets.

Development

Development for this issue will go into the dev-121-multi-target-workflows branch to eventually merge into v4/main. The subissues (and associated pull requests) will merge into this dev branch as well, so the overall pull requests will not be too large.
