Flux-style Helm Release versions including OCI artifact ID are not recognized by Nova

[fibbs]

What happened?

I am using Flux to manage my clusters. When using a Flux HelmRelease resource together with a OCIRepository, having the HelmRelease referencing to an artifact in the OCI repository which is the helm chart, which is the new standard, the Helm Release version is represented concatenating the Chart version from the chart's Chart.yaml with the OCI artifact hash (or something like that):

helm ls
NAME    	NAMESPACE	REVISION	UPDATED                                	STATUS  	CHART                       	APP VERSION
keycloak	keycloak 	11      	2024-12-26 19:21:36.413229479 +0000 UTC	deployed	keycloak-24.3.1+dbae01c0bd1d	26.0.7

Now, when using nova, it doesn't recognize this version as being the same as the upstream one:

Release Name              Installed              Latest           Old     Deprecated
============              =========              ======           ===     ==========
keycloak                  24.3.1+dbae01c0bd1d    24.3.1           true    false

What did you expect to happen?

I would have liked Nova to recognize this special versioning and "understand" it. Or to be able to configure this somehow (see #353).

How can we reproduce this?

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: OCIRepository
metadata:
  name: keycloak
  namespace: keycloak
spec:
  interval: 12h
  provider: generic
  ref:
    tag: 24.3.1
  timeout: 1m
  url: oci://registry-1.docker.io/bitnamicharts/keycloak

apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: keycloak
  namespace: keycloak
spec:
  chartRef:
    kind: OCIRepository
    name: keycloak
  interval: 1m0s
  releaseName: keycloak
  valuesFrom:

Is this versioning string specific to flux, or is it how Helm shows the version when installing from an OCI registry? I don't believe I've seen this before.
