In `@charts/janssen/charts/auth-server/values.yaml`:
- Line 29: Remove the extra space after the colon for the YAML key "repository"
in values.yaml (the line showing repository: 
ghcr.io/janssenproject/jans/auth-server) so it reads with a single space after
the colon ("repository: ghcr.io/...") to satisfy yamllint's "too many spaces
after colon" rule.
