Further Linux integrations [epic]

[prusnak]

1. Install handlers (these should be possible via already deployed AppImage, but will apply for other methods below):

• [x] udev rules - https://github.com/trezor/trezor-suite/issues/3664
• [ ] desktop file
• [ ] URI handler (this is probably done via desktop file)

2. Enable new Linux build targets:

• [ ] DEB (signed with GPG)
• [ ] RPM (signed with GPG)

3. Create repositories:

• [ ] for DEBs from step 2 via createrepo (see below)
• [ ] for RPMs from step 2 via dpkg-scanpackages (see below)
• [ ] Snap https://github.com/trezor/trezor-suite/issues/3696
• [x] Flatpak https://github.com/trezor/trezor-suite/issues/3697
