Add in-app changelog

[micahmo]

Pull Request Description

This PR adds support for an (optional) in-app message and changelog for when the app is updated.

• This is optional, and while it's on by default, there's a single button which users can press to disable (without having to go into settings).
• No notification is shown the first time the app launches, only when the version is detected to change.

Screenshots / Recordings

Note

In this demo, I have the dialog appearing for every restart of the app so I can demonstrate the settings. In reality, it should only appear when the version has changed.

I think it looks good! Just a couple of minor things:

• For the settings label, we can reword it to "Show Update Changelogs" (the subtitle can be left as is)
• For the bottom sheet title, we can rename it to display "{version} Release Notes" (e.g., v0.3.0-1 Release Notes). I think that's a bit more concise than what its set to right now!
• I'm not sure how I feel about having 3 buttons at the bottom. Ideally, I'd like to reduce it down to two ("Close" and "Disable Release Notes"). I did try to experiment with the changes to see if I could use something like a DraggableScrollableSheet so that we don't need to have the "Expand" option, but I wasn't able to get it to work just right. I think we can leave it as is for now (but maybe subject to change in the future)

Done! I went ahead and refactored the whole setting to use this new name.

Hmm, we can certainly tweak the wording. I did write it intentionally so that it comes across as an announcement. I think it's pretty common for apps to tell you that they updated, and it's a nice reminder for those who use automatic updates (and maybe don't care as much about the changelog).

If you want to save some room, how about something like this?

Otherwise, if you feel strongly about your wording, of course I'll be happy to defer.

I'm not sure how I feel about having 3 buttons at the bottom. Ideally, I'd like to reduce it down to two ("Close" and "Disable Release Notes").

Fair enough! I removed expand/collapse. I did expand the default height a bit as a compromise. Hope that's ok!

Thanks for the changes! I think all of the changes were reasonable!

Oops, I didn't push the title change. Let me make a new small PR for that.
