fix(opener): use the correct packagename in OpenerPlugin.kt

[universalappfactory]

The packagename in OpenerPlugin.kt was set to 'package app.tauri.shell' which leads to an ClassNotFoundException when using android as the PLUGIN_IDENTIFIER in lib.rs is set to app.tauri.opener.

I fixed the packagename according to the value in lib.rs (app.tauri.opener)
