Upgrade GitLab Pages to v0.5.0

See merge request !12625

This works exactly like the same param when merging an MR.

We don't need this in the UI, because you already get a warning in the widget
when the source branch HEAD changes while you're on the page.

If the `max_file_size` parameter were not specified, Grape would
default that value to `nil`, which prevents the model from being
validated and saved. As a result, users would see a JSON response
that had an `id` of `nil`, and the push rule was never created.

Closes #2820
