chore(charts): change URL of image repo to ghcr.io in sub-charts

[iromli]

Some of the sub-charts use URL of image repository to the old ones (docker.io):

» rg repository:
charts/config-api/values.yaml
32:  repository: janssenproject/config-api

charts/auth-server/values.yaml
29:  repository:  janssenproject/auth-server

charts/saml/values.yaml
28:  repository: janssenproject/saml

charts/auth-server-key-rotation/values.yaml
19:  repository: janssenproject/cloudtools

charts/persistence/values.yaml
19:  repository: janssenproject/persistence

charts/scim/values.yaml
29:  repository: janssenproject/scim

charts/config/values.yaml
155:  repository: janssenproject/configurator

charts/fido2/values.yaml
30:  repository: janssenproject/fido2

charts/casa/values.yaml
28:  repository: janssenproject/casa

These URLs need to be pointed to ghcr.io.
