Try web-ext

Trying to use web-ext to handle lint, build, and packaging.

Currently struggling with manifest.json handling since web-ext doesn't handle a custom manifest file specification for its commands.

Worked around the manifest.json issue by copying the right one before each build / run tasks. A bit clunky but works.

web-ext run tasks work, however the Firefox one is buggy on Ubuntu because it's installed via snap. As a workaround, I'm thinking about using DevED instead of stable release, which could be installed without snap on Ubuntu and should be available at Orange.

FWIW ESR is not available without specifying its path, making this option useless for cross-env work.

Keeping as-is for now: npm run load:firefox should be tested on Windows — and for Ubuntu users (like me), Firefox testing still needs to manually load extension through about:debugging.

To give some background:

• using devEd (installed manually) doesn't work either,
• we may launch web-ext through Node with env-paths to make cross-env paths to Firefox bin / cache, but that require a bit more work.
