Add support for Vanadium (the default browser of GrapheneOS) to the android app

Hello, I am a privacy-focused individual and am using GrapheneOS to reduce the tracking Google and Google Play Services can do.

Can you please raise a ticket to add Vanadium as a supported browser? Its based on Chromium and the patches that are made to Chromium can be viewed https://github.com/GrapheneOS/Vanadium. Most of it is just upstream Chromium, as such it has the same support for autofill that Chromium has.

Thank you!
