Documentation updates to gcp module credentials (!463) · Merge requests · GitLab.org / GitLab Environment Toolkit

What does this MR do?

Adding auth_kind to vars.yml did not work for me, it needs to be added to the *.gcp.yml file and not vars.yml.

There was also a better page for understanding GCP plugin credentials, so I've swapped the old link with this one.
