🔧 migrate the developer-extension to wxt

[BenoitZugmeyer]

Motivation

The webpack configuration for the devtools extension is rather tedious to maintain. WXT offers a better DX out of the box, with a single dependency.

We tried going with a basic Vite config file, but it was proven too cumbersome because of the need to use one config per entry point.

Changes

Replace webpack with WXT

Test instructions

In the extension folder, run yarn dev to open a browser with the extension installed.
You can also run yarn build to build it.

Should we clarify why we need this? As we didn't have it before.

[BenoitZugmeyer]

We did have it before, just not as a separate file. I linked to MDN docs in the README to clarify a bit the architecture.

I think we could remove the suggestions/warnings from the build so we don't have so much noice the terminal?

I removed the warning. I don't think we can remove the dotenv log / tip unfortunately. I'll see if we can avoid building the extension when running yarn build at the toplevel, to reduce the noise there.

Excellent, sounds good!
