Use exact match with project name on CI pipeline
While we tackled the problem at !928 (merged), we could use one of more simple tips, used in gitlab-org/gitlab etc, which is the exact match with project name instead of regexp pattern match.
Context
I am not sure why can't we use
$CI_PROJECT_PATH == "gitlab-org/gitlab-docs"'here🤔 . See the similar in gitlab-org/gitlab: https://gitlab.com/gitlab-org/gitlab/-/blob/0615efc08e6f5dd19b81cb313db9733b01727ae7/.gitlab-ci.yml#L33
