[Stimulus] Update hotwired/stimulus to v3.0.0-beta.2

[seb-jean]

Hi,
Stimulus is in version v3.0.0-beta.2. It would be great to have to update it in symfony/ux 😄.

Thanks :)

Thanks for the issue. This is actually not going to be so simple. Here is beta 1: https://github.com/hotwired/stimulus/releases/tag/v3.0.0-beta.1

I believe the only big thing is the package name change, which is significant - to @hotwired/stimulus.

However, beta 2 is a bit more concerning, specifically this: hotwired/stimulus#444 - that removes the Webpack support. We could include that in our package - but we should check to see what other approach Rails is doing to see if that's where we should go.

Stimulus 3 is release today! : https://world.hey.com/hotwired/stimulus-3-c438d432

The _dispatchEvent functions may be removed. this.dispatch can be used : of hotwired/stimulus#302

Webpack support seems to been released in a separate package: https://github.com/hotwired/stimulus-webpack-helpers.

Rails 7 will default to import-maps (see https://world.hey.com/dhh/rails-7-will-have-three-great-answers-to-javascript-in-2021-8d68191b)

Yup - I had missed this originally. So the quick path that we should take is to use that new package from inside of stimulus-bridge: https://github.com/symfony/stimulus-bridge. Unless we're able to work some magic (which I'm not sure is possible), this will likely cause us to need to trigger a new major release in that package.
