Reflect default browser changes in bindings and webapps (#871)

* Abstract default browser to omarchy-browser (a wrapper)

* Fix the omarchy-browser command as it used to loop. Extract info from the browser .desktop files.

* Clean up and fix bugs

* Cleanup unused change

* Fix indentation

* Separate out omarchy-browser from omarchy-webapp so that we don't break webapps for browsers other than Chromium or Google Chrome.

* Fix incorrect function call

* Add a migration script

* Migration script fixes

* Simplify the browser and webapp commands. Rename commands to align with launch terminology.

* Add support for Microsoft Edge, Opera and Vivaldi

* Fix errors

* Remove --name and --class -- They're not respected when --app is defined

* We don't ship with Chrome

* Simplify launchers

* Use launch commands everywhere
