In 2020, a change (0ebfa480a6) was made to ChangeFormPageView that

updated a render() call to renderPage(). This was done as part of a

series of fixes to page rendering, except that this particular update

was made to an AdminInlineGroupView. This function doesn't exist

there, so this failed. Apparently this has gone unnoticed, and wasn't

really that big of a breakage.
This change fixes that call, reverting it back to a render(). This

will be backported to 4.0.x.

Loaded the User change page. Verified it no longer errored out with

an invalid function call.
