Fatal error due to saved additional form IDs being strings and not arrays

Was this fixed in 🐛 Config schema errors Fixed ? Or is it partially fixed?
The merge request here is all about arrays, while the other issue further stringified things.

And more: 🐛 Argument 2 passed to _readonlymode_form_list_check() must be of the type array, string given Active

Don't be mad y'all, I know there are plenty of conversations around uploaded patches vs. using MR generated patches locally. For me, I'm contributing this patch to another project that doesn't have local patches, so I want a permanent link. So far as I can tell this is not yet supported in GitLab.

Patch in #23 did not work for me on D10.

In admin/config/development/maintenance, I got:
TypeError: implode(): Argument #2 ($array) must be of type ?array, string given in implode() (line 102 of modules/contrib/readonlymode/readonlymode.module).

I could get a no error or warning install using

2. Using https://git.drupalcode.org/project/readonlymode/-/commit/2ef5cf6e49dbcca... fixed Warning: Undefined array key "show_view_elements". Credit to Ben Teegarden
3. There was also a "Warning: Undefined array key "actions"" in some administrative pages that I fixed appending the 'actions' key just like in item 2.

Just fixing filename from #24.

Same patch as #24 but remove only 'show_view_elements' element from form.
