tauri: migrating to V2

[xTVaser]

Fixes #529 and #224
Fixes #581

May potentially solve #581 as it uses a newer version of webkit2gtk -- im currently convinced the UI rendering bug is the fault of webkitgtk2, and i tested last night that on newer versions (i used GNOME Web) it doesn't manifest.

• Confirms to solve the issue, though it causes others 😄 https://bugs.launchpad.net/ubuntu/+source/webkit2gtk/+bug/2081166

Before merging:

• make sure the release process works (test on a fork)
  • don't forget to do ci: simplify generation of release metadata file #224
• test on all operating systems
  • windows
  • macos
  • linux

This is blocked for the following reasons:

• Linux
  • [bug] broken IPC in multi window app on Linux tauri-apps/tauri#11171 (our app is multi-window and it doesn't seem to work properly, i had to temporarily make it a single window app to get it to even launch)
  • [bug] Tauri 2.0.0-rc shows blank window after upgrading to webkit2gtk-4.1 2.44.3-2 tauri-apps/tauri#10626 (bad webkit version out there? upstream ubuntu bug report https://bugs.launchpad.net/ubuntu/+source/webkit2gtk/+bug/2081166)

Both linux related tauri bugs have been closed.

tauri-apps/tauri#10626 (bad webkit version out there? upstream ubuntu bug report https://bugs.launchpad.net/ubuntu/+source/webkit2gtk/+bug/2081166)

If the Linux version is to be released only as a Flatpak, this is not an issue as the webkit version is controlled in the Flatpak sandbox. This is done through the runtime sdk selection and not the system libraries.

It was an issue because you couldn't develop or debug the app on ubuntu linux.
