feat: Notebooks History

[benjackwhite]

Problem

We autosave changes which is great but sometimes you might make a change and think "whoops - I want to revert".
Undo redo works whilst the Notebook is open but after that you might want to revert to a previous version.

Changes

• Adds a popout to the sidebar for the "history" using the Activity API.
• Selecting an option previews it, which copies the old content out and saves forward.
• Fixes scrolling to a node, to only do it when the settings are opened.

TODO

• Actually implement the revert
• Fix the UI / styling
• Maybe preview the change?

This is awesome... a few nitpicks but otherwise 🚢

If there's only a single version and I open the history, then I can click on it and am offered the opportunity to revert. Really the current version shouldn't offer that option

---

My first instinct to close the history was to repeat the action I'd done to open it...

For 100% score on the PR it'd be awesome if the activity log distinguished between a revert and a not-revert

But that's very finicky of me

That's a good point! Modified it to show the "created this" state for the very first activity and mark the "current" version as current so that you can't revert to it.

It is now a toggle

Yeah I thought about this. The tricky bit is it is more of a "revert commit" so there's no current way of distinguishing it.
We could perhaps add some meta fields to the content but I want to avoid making a schema decision here. Good idea for follow up though.

If we had a field to say something like "version this was copied from" that could be stored somewhere, at least in the activity log maybe 🤔

Ah, I was too slow :D

A couple of nits, but not blocking so 🤷

• when you create a notebook from a previous version the toast says you created it from a template, but you didn't
• if you have the history panel open and edit the notebook, it doesn't automatically reload, so you have to close and re-open it to see the current history
