Field Widget broke in translation node

Updated patch to not only affect available block list, but configuration of the field itself.

I think need replace "Category" plugin to Provider. Provider (always) = module_machine_name

Add new plugin, Filter by providers.

#10 patch works for me in Drupal 10.2.5 and Drupal 10.3.0

For me, what I was testing was, Content Block being translated to Bloc de contenu from English to French.

If Content Block was selected as a category in English, then Bloc de contentu would not be selected in French.

The patch on comment #10 resolved this without having to modify the translation.

#12 patch unfortunately didn't seem to work for me in Drupal 10.

Thank you all!

Please prepare a MR instead of patches for review.
