[ckeditor5-inspector] Add history/operations/batch tab

[rshipp]

📝 Provide a description of the new feature

Display the history stack, and some way to look at batches/operations and have a basic understanding of what they're doing (e.g. InsertOperation on path [1, 0, 0, 1]). I know undo/redo is an optional plugin, so I'm not sure if this'd be in-scope for the inspector, but it'd be super helpful for me.

My use cases:

1. I have a bunch of custom components, and I've noticed some of them seem to be breaking undo/redo functionality. When I insert them via a Command, then try to undo, they aren't removed from the editor. I'm going to have to debug why, and it'd be convenient to have an easier way to explore the history / undo batches than clicking through things in the console.

2. I'm building some persistent undo/redo functionality, where undo batches and operations are stored to a server and manually loaded back into the editor on pageload. This also has me debugging a bunch of batch/operation stuff manually from the console.

Hi, @rshipp!

Thank for your suggestions. That would definitely help a lot of people figure out some operation mess in their projects. I can't give you an ETA because there is plenty of other improvements already on our TODO list but I promise I'll keep it in the back of my head 😀

Oh, BTW, since you're here, can I ask you to skim through existing issues and give 👍where it makes sense for you? That would help us a lot in the future.
