Update mobile docs to include new cargo-mobile2 template

[matthunz]

Includes the new cargo-mobile2 template from https://github.com/tauri-apps/cargo-mobile2/pull/357

Readers can now get started faster with cargo mobile new and selecting the dioxus template.

Does this work on windows? I ran into a linker error with android on macos

Huh sorry actually Android does seem buggy :thinking:

I've been having trouble with cargo-mobile2 compiling for Android for a little while now so I just filed https://github.com/tauri-apps/cargo-mobile2/issues/392.

After compilation however the screen appears blank :eyes: not sure what the error is here yet since I don't see any logs. Blitz does still seem to be working https://github.com/matthunz/blitz-android
