Production publishing job

[sublimator]

Using GH Actions:

1. On every tag (e.g. [email protected]) pushed
2. (For browser in Firefox, Chrome, Edge, etc) create the assets required for manual publishing
   • Firefox needs a zip of the source code (Github has handy links for this which could be used)
   • Make sure the extension builds are using that source archive that is created for submission
   • [email protected] etc
3. Store the assets somewhere handy (Does GH have some facility feature for artifacts of actions?)

• [x] #3115

Old:

1. On a merge to main
5. Check if the manifest version changed
6. If Yes -> Build all versions for the stores
7. Manual hold step which is then used to publish to the stores.

Preferably using Github Actions

@wext/shipit seems to fail a lot for FF add-ons, however the builds are published
