Setup a CI/CD system for testing critical extension features before release

[GaurangTandon]

This is a list of features I'd like to test before every release:

Functional

1. Context menu/hotkey snippet insertion, with and without placeholders, in both contenteditable and textarea editors
2. Mathomania in both types of editors
3. Auto-inserts
4. Tab key as four space
5. Omnibox support works
6. Site blocker working - both via settings page and context menu
7. Disabling ctx menu works

Options page UI

1. All UI elements behave as expected

Sync storage

This one's a bit tricky to test, any idea how we would do that?
