`wp_get_post_revisions()` should have a default `orderby` of `date ID` to tie-break rapidly added revisions - namely, when unit tests are run. There is a test that occasionally fails when running all tests, and always fails when running `phpunit tests/phpunit/tests/post/revisions.php `. This fixes that.

Fixes #26042.
