Field formatter: Add a setting to disable the "Add" button

It is designed with permission to add paragraphs

@lazzyvn: Would be great, if you'd think about our offer for the additional setting here again. At least for admins, the permission will never do anything (because they have all permissions) and it's not untypical that you simply don't want the Add feature, so I'd really expect a setting next to the existing line acton settings.

I think it would be helpful in sbx. But of course you decide as maintainer :) We'd sponsor it with our time.

You can active module 'Paragraphs Type Permissions'. You can set role to see button add or use css to hide it

@lazzyvn thanks. We still have the issue that the button is visible for user 1 - the client - who is confused and complaining.

Do you see a chance to reopen this and allow disabling the add button entirely or at least add a possibility to alter it using hook_paragraphs_table_formatter?

Or would you at least allow adding a dedicated class to the button and its wrappers so it can be cleanly hidden by CSS?

@lazzyvn I created a MR for adding the classes, maybe that would be okay for you?

Was merged - with no credits yet.

Leaving this RTBC because of the missing credit.

I still credit you but this patch is really not serious at all. It almost didn't check it again before merge request, it caused an error when checking so I had to fix it.

Sorry @lazzyvn you're right, that was indeed too quick.
