feat: switch to the Firefox Stable equivalent by default (#6926)

This patch:
- starts downloading Firefox Stable equivalent by default
- starts running Firefox-Stable on our smoke tests (tests-1)
- starts running Firefox-Beta on our CQ1 tests (tests-2)

Note: there's a little confusion right now with browser names:
- `firefox-stable` - firefox-stable equivalent
- `firefox`- firefox-beta equivalent

I'll rename `firefox` to `firefox-beta` in a follow-up.

Fixes #6817
