BlockPatternSetup enhancements

[jcheringer]

What problem does this address?

Jetpack Forms (Form block) has received several improvements recently.
One of them was the possibility of exploring Patterns right from the Form block placeholder.

For that implementation, we followed the suggestion of using the BlockPatternSetup as it was used in the Query Loop block.
It served our purposes well, and now we'd like to propose a few improvement points we noticed and/or received as feedback:

• The default modal viewMode is set to Carousel, and it's not possible to change it externally. In certain scenarios, the Grid view is more suitable, so it'd be great if we could choose the default viewMode.

• The modal doesn't show the title and/or the Pattern's description. For some use cases, showing a title and/or a description of the Pattern would make it more apparent to the user the purpose of the Pattern.
  There's already a discussion about this topic(Pattern Inserter: consideration to always show each pattern title #45595), but it applies to another visualization of the Patterns. We want to use this opportunity to leave our 'vote' in favor of showing, or at least have the possibility to show the title and/or Pattern's description.

• We got some feedback that, when previewing the Patterns in the Carousel viewMode, sometimes the next/previous slide is shown briefly during the transition and the view is a bit shaky. The same issue can be noticed using the Query Loop block.

Please let me know if I can clarify or if you need more details for any of the points above.

@ntsekouras curious if you have time to review this and share some thoughts based on your work in general with patterns and the query loop block.

Thanks for the issue @jcheringer!

The initial view mode suggestion has already landed.

The modal doesn't show the title and/or the Pattern's description.

I created a PR for the inserter list and I guess the discussions will dictate the way forward for this one.

We got some feedback that, when previewing the Patterns in the Carousel viewMode, sometimes the next/previous slide is shown briefly during the transition and the view is a bit shaky. The same issue can be noticed using the Query Loop block.

Maybe a small video for this would help..

Hey @ntsekouras, thanks for starting to handle those!

Here is a recording from the Query Loop block

And here is one from the Form Block

Agreed.
