🔧 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.
