[FRQ] Open author+non-article URLs in a popup in the WebView

[MrDevel0per]

Is your feature request related to a problem? Please describe.
Not really, but this would help with going back on WebViews - if we open another URL directly in the WebView, it's hard to go back to the article, and once we impliment saving etc. features it will be harder if we have a direct save button on a nonarticle URL.

Describe the solution you'd like
When the user clicks on an author URL or a link to a different webpage, the URL should open our WebView, but in a SwiftUI .sheet popup. This is like how Apple News does it, except they use a .fullScreenCover.

Describe alternatives you've considered
We could continue opening the URLs in the WebView - that's what we're doing right now. However, this has some drawbacks as noted above. I believe this is the best solution.

Additional context
Do we want to have the sheet go fullscreen with .fullScreenCover or do we use a .sheet only?
