Add support to implement formatting toolbar buttons in TipTap

[srdjanmarjanovic]

It would be great to have the ability to format comments with at least bold, italic, underline, link, ordered list and unordered list TipTap marks via toolbar. Unfortunately, at the moment there is no workaround to implement this in our projects and require the package to be updated.

Syntax like the default Filament v4 RichEditor would be awesome:

CommentsEntry::make('comment')
    ->toolbarButtons([ 
        ['bold', 'italic', 'link', 'h2', 'h3'],
        ['grid', 'attachFiles'],
    ])
