Feat: Wrap multiple elements using the new picker

[liady]

Problem:
Our current picker does not support multiple selections, we need this functionality for wrapping multiple elements

Fix:
Make the new picker accept multiple selections.

Important note: this PR adds the functionality of wrapping multiple elements, but for replacment and inserts the target remains only the first selection (as it was before).
We need to decide later on what to do about insertion/replacements

I've left a message on discord about special casing some wrap behaviors for div, fragment and group

[balazsbajorics]

we should not forget about re adding the special cased wrapping behavior for div, group, fragment

[seanparsons]

Better to avoid those subscripts because they're a bug waiting to happen.
