Show release notes locally when showing update notification

[JosephTLyons]

Closes #17527

I think we are ok to switch to using the local action now. There are a few things we don't support, like media, but we don't include media directly too often, and I think this might help push the community to maybe add support for it. That being said, I updated the markdown coming back from the endpoint to include links to the web version of the release notes, so they can always hop over to that version, if they would like.

Screen.Recording.2024-09-28.at.2.13.16.PM.mov

All forming of the Markdown happens in the endpoint, so if someone with a better eye wants to update this, you can do that here:

Release Notes:

• Changed the view the release notes button in the update toast to trigger the local release notes action.
