[WEB] Feature request: Support WASM by migrating to package:web

[gabrielginter]

Flutter Web WASM-GC support is now available on the beta channel, it would be great to have Pusher WASM ready.

Package web migration guide: https://dart.dev/interop/js-interop/package-web

Based on the Flutter release schedule it is likely WASM support will arrive tot he stable channel in 3 months, it would be great to be ready for it.

Hi, I will pass this request to the team to look into, however at this time we can't commit to a release timeframe

@benw-pusher Version 3.22 has been released with WASM support in the stable channel, the only package that is blocking me from compiling to WASM is Pusher sadly. I think the migration is fairly simple.
