We can deploy phpDocs in safe environments only, but "safe environment" is equivalent to "pull a local branch", therefore we can simply use that local branch to deploy the phpDocs. There's no need for a explicit pull request support.

holds the SHA of the merge commit and not of the
latest commit of the head branch, therefore the comparison fails. We could
theoretically compare it against this attribute, but as of its deprecation,
this is a pretty bad idea. Thus we remove the latest commit check for pull
requests.
