Revert "Add question about what to do when there are major changes at a forge"

This reverts commit b358c3d2. This
update is not ready yet. Quoting pabs:

> […] I noticed that resubmitting a forge using the same URL and a
> different forge type is blocked with Request for forge already exists
> (id 240) when the forge was already added via Add Forge Now. So this MR
> will need to wait for a fix for that issue, or the process for
> submitting forge updates will need to be rethought.
