fix(mirrorbits): use the PVC name defined in values.yaml everywhere

[lemeurherve]

As it is currently, even with a repository.name value specified in values.yaml, the PVC is named only in the PVC template, it has a generic release name + "-binary" in the deployments templates.

This PR fixes that.

Note: I don't see why there are $. in front of some of the if in these deployments an in the PVC template 🤔

Good catch 👍

As this chart does not have any unit tests, I've tried an helmfile diff against the production cluster publick8s and the result looks good:

helmfile diff -f ./clusters/publick8s.yaml -l name=mirrorbits --suppress-secrets --skip-deps --context=2
