Add paragraphs search functionality

Hi @vishal-yaduvanshi

I have had the same problem and I think it would be a good idea to have a paragraphs type finder so I have made a patch that I think you could use.

hey @cmarrufo

thank you for your response, this functionality is very useful for me and the community of Drupal.

Looks intersting, but all non-trivial contributions must be merge requests now. A test would be great as well, but I can live without for non-critical functionality.

   if we stick with a server-side implementation then this should override the getEntityListQuery() method, so we don't need to query and list twice.

   would it make sense to default the focus on this field, then you can visit and type immediately.

   I'm also wondering if this should be a client-side functionality, similar to how \Drupal\views_ui\ViewListBuilder::render does it. That would require no reloads. would require to disable the pager, like views does.
