Can't set externalClusters

[Ofirfr]

Just as title, the helm chart does not support setting externalClusters field, the field can be seen in docs:
https://cloudnative-pg.io/documentation/1.24/database_import/

The chart is responsible for filling in the externalClusters section based on your recovery configuration. I don't want to expose it.

Import is not yet supported. There is a PR that adds support for it, but I probably won't get around to merging that soon.

If you need import, for now, I would suggest you interact with the operator directly i.e. don't use the chart.
