doc: Warn for support drop of postgresql 11 in version 14.0

See merge request gitlab-org/gitlab!64763

Includes predicates as methods to avoid returning nil instead of false

Also adds the tests to EE as a shared example

The remaining methods delegated to ci_cd_settings also caused error
500 when the CI CD settings are deleted but the project still exists.
This allows them to return nil instead of raising an error.
