v4.0.0-beta.4

✨ Initial Wasm support (#5458)

This release adds initial support for WebAssembly by adding the wasmJs target.

Executing queries/mutations is working but this target is experimental (Kotlin/Wasm is Alpha) and has multiple limitations:

• No WebSockets
• No caching
• No support for WASI or NodeJS

🪲 Bug fix

Downloading a schema from introspection (./gradlew downloadServiceSchemaFromIntrospection) got broken in the previous release (#5449) and is now fixed.
