I found out later that the base64 string in the certificate-authority-data of the .kube/config file that I was coping its content into the CA Certificate field of GitLab "Add Kubernetes cluster" form, it is the PEM format, but base64 encoded.

The PEM format already is a base64 encoded representation of the certificate bits, but it has some line breaks in the middle. This whole content is base64 encoded again before it goes to the .kube/config so it is turned into a big base64 single-line string.

I just had to base64 decode this big single-line string (I used the javascript atob("....") in the Chrome's Console window), what gave me something like this:

-----BEGIN CERTIFICATE-----
MIIEyDCCArCgAwIBAgIRAOL3N8oMIwWIxcFTZhTkfgMwDQYJKoZIhvcNAQELBQAw
...

cUp3vlwRITrv0mzrxiQjTLTUpEy7EcD+U6IecA==
-----END CERTIFICATE-----

Then I just copied this content into the GitLab "CA Certificate" field and it worked.
