Update web implementation to depend on Dart 3.3 JS interop + the recommended web package

[davidmartos96]

Fixes #24 and #28

The following PR updates de Web code to depend on the enhanced JS interop solution Dart provided in version 3.3+
The js dependency and dart:html are dropped in favor of web and dart:js_interop https://dart.dev/interop/js-interop
Migration: https://dart.dev/interop/js-interop/package-web

This seems to be the approach the official plugins are starting to take for the web implementation

For some strange reason the CI is failing to start the iOS Simulator. Doesn't seem to be anything related to the PR changes, but it worked correctly for a previous run 2 weeks ago.

Can we guarantee that this doesn't require the latest versions of Dart and Flutter?

Just trying to not limit this based on just the newer version.

[davidmartos96]

I'll check later, although my understanding is that it's only available from Dart version 3.3.
In fact, the pub.dev web package has 3.3 as a constraint, and it's what the team is starting to push forward to be compatible with WASM.

Yes, js_interop is available only since Dart 3.3 https://medium.com/dartlang/dart-3-3-325bf2bf6c13, so there is no way to have older versions supported.

[diegotori]

Understood.

When I get back on Monday, I think we'll have to make this a major version so that it's distinct from everything up to this point.

chewie will also have to be bumped up due to this, since it makes use of this library.

[vbuberen]

Sorry for adding some work. Had users requesting to support WASM and agreed to do the migration in Plus Plugins

@davidmartos96 please re-sync your changes with main's latest ones. Thanks.

@diegotori I think you can turn on this option in the repo to get a button to do such syncs yourself as well.
Check General section of repository settings and find options Always suggest updating pull request branches:

I didn't know that was an option in the repo. I was confused that the option to update with master wasn't there.

LGTM.
