Paragraphs (stable) title from form options not being applied.

Here is a patch.

Made some further improvements so that renaming the field is not needed at all.

I've tested both patches and they both work. Nice job(s), thanks!
Personally, I'm going with #2 at this time. I'm not seeing the advantage of #3, and that version seems to do a little too much. @Meleagyr, perhaps you could explain the use case for #3? Maybe I'm just missing something.

Update:
Actually, there is an issue when a field can take multiple paragraph types. Instead of displaying each paragraph type in the drop button, the displays the Title text for all, so there's no way to distinguish among them. See attached images.

Added both patches in 1 MR. The MR is the latest patch from #3
Will test what msypes describes

Trying to reproduce the issue in the first place, but not able to do so. Is anyone else able to reproduce this?

Same problem here, the single title should only apply when you have only 1 possible paragraph for a field.
I guess the problem is more complex when you have more paragraph possible, to be able to override them.

If the current last patch is altered to apply only when there is only 1 paragraph type possible for the field, it would do for the current case (1 paragraph type selected for the current field) with the current settings available.
