Feature: Make it possible to select a preferred browser

Hello,

I noticed the Browser Preview should now supports Microsoft Edge, but I don't see any option for switching between the browser engines.

I changed the 'Chrome Executable' in the Settings, however I get an error and it's probably not even the correct way of changing it.

Any ideas?

Start by tracing how the current Chrome Executable setting launches Browser Preview and how Microsoft Edge support is represented. Identify the entry points and settings involved, then determine what browser choices must be exposed and how the preferred choice should be persisted. Done means users can select a supported browser without the current executable-setting error.
