When referring to external issuers whose kind is not "Issuer" or
"ClusterIssuer" we log an error message thanks to a new check added in
a previous PR[1] which should only trigger for SelfSigned issuers.
The error previously looked like:
```text
"error"="invalid value \"x\" for issuerRef.kind. Must
be empty, \"Issuer\" or \"ClusterIssuer\""
```
After this PR, any CR with an issuer whose group or kind doesn't
match what's expected for a built-in issuer will be skipped
