Feature: Add shortcut to enable Rearrange View

[maxthyron]

Read the comments about adding a new shortcut, hope this is how it should be done.
Added some checks for opened split view menu and that split view is enabled.

I don't know how to properly add the name for the shortcut in the menu and translations for it, since they seem to be in a separate repo.

Additionally while testing I needed to create a new profile for new shortcut to show up, is this intended behavior? Or do I need to remove some cached files for changes to apply?

There are also a typos:

1. in the function's name afterRearangeAction -> afterRearrangeAction
2. this._thumnailCanvas -> this._thumbnailCanvas

Not sure if it's suitable to add here too.

Lastly, I had to disable Prettier for the project because applying the default prettier config from the repo messed up some files I opened, at least ZenViewSplitter.mjs has some inconsistencies(e.g. _swapField function has some strange whitespaces)
