Add workaround for broken AppImages

There is a bug in libwebkit2gtk that prevents a tauri AppImage from
working. To work around this bug we downgrade libwebkit2gtk and
associated libraries in the build workflow on CI.

See https://github.com/tauri-apps/tauri/issues/11994 and
https://github.com/gitbutlerapp/gitbutler/pull/5301
