Description

[!NOTE]

• This issue is blocked by #607 where the new version will be made that this work can be based off of

Once #607 is finished, it would be great if we converted the About tab of the Scribe keyboard app over to using Swift UI. This should roughly follow the code that's developed in #607, with minor changes for some of the menu options for the keyboard app. The Figma designs for the keyboard About tab can be seen here.
