[Documentation] Fix minor issues in search API doc

Closes #54959

See merge request gitlab-org/gitlab-ce!23645

If a commit has two parents, one is direct ancestor, and one is not,
and the order of `commits` is in such fashion that the non-ancestor
side is visited first, the commit would be determined as non-ancestor,
when in fact it can be.

Therefore we should first determine all direct ancestors
prior to analyzing.
