How can I know what the latest supported kubernetes version is and which latest vcluster helm chart is compatible?

I can see in the logs version 1.27, will fallback to virtual cluster version v1.24, but it would be nice to know ahead of time what the latest and great version is, or to be able to just select the newest available. Also, the above is failing, but if I go back to vcluster v0.13.0 it works. How can I know these two values ahead of time rather that by trial and error?

This is probably a duplicate of https://github.com/loft-sh/cluster-api-provider-vcluster/issues/39 - right?

[lknite]

This issue is more around knowing what to put in the yaml, than asking for a new version (though I am interested in newer versions as everyone else).

Potential solutions would be to allow no versions in the yaml and the latest will be selected automatically or a chart at github with supported versions.

Otherwise, it seems like just selecting a very high version would be a good "hack", but I'd rather not guess, and am will to go somewhere to look it up.
