Raise default CI variable limits

Data gathering revealed that the maximum number of CI variables
currently used by projects and groups on gitlab.com is much higher than
we originally suspected. This commit raises the default variable limits
so that enforcing them on the backend will not be a breaking change

Changelog: changed
