Use tauri v2

[fossdd]

Describe the problem

tauri v1 (which is currently used by cinny) uses webkit2gtk 4.0. However webkit2gtk 4.0 is outdated and unavailable on many distribitions like Debian or Alpine (which I was packaging Cinny on).

Unfortunaly I have to disable the cinny package on Alpine Linux since we removed webkit2gtk 4.0 and only support webkit2gtk 4.1 or 6.0.

Describe the solution you'd like

Ideally cinny-desktop could be moved to tauri v2 which supports webkit2gtk 4.1 and would restore support for many distributions.
