Bump to v0.11.0, update CHANGELOG.md & Example (swiftwasm#143)

I had to remove SwiftWasm 5.3 and 5.4 from CI because OpenCombine/OpenCombine#225 is reproducible with all code, not just OpenCombine, with old toolchains when Xcode 13.1 is installed.

I've also updated `Example` code to try using `fetch` with `async`/`await` and a section with a simple guide for this to `README.md`

Node.js and npm dependencies together with webpack.js config in `Example` directory were also updated.

* Bump to v0.11.0, update `CHANGELOG.md` & `Example`

* Add simple `async`/`await` guide to `README.md`

* Use `wasm-5.5-SNAPSHOT-2021-11-20-a`

* Update `CHANGELOG.md`

* Update `.swift-version`

* Add acknowledgements to `CHANGELOG.md`

+# 0.11.0 (22 November 2021)
+
+This release adds support for `async`/`await` and SwiftWasm 5.5. Use the new `value` async property
+on a `JSPromise` instance to `await` for its result. You'll have to add a dependency on the new
+`JavaScriptEventLoop` target in your `Package.swift`, `import JavaScriptEventLoop`, and call 
+`JavaScriptEventLoop.installGlobalExecutor()` in your code before you start using `await` and `Task`
+APIs.
+
+Additionally, manual memory management API of `JSClosure` has been removed to improve usability.
+This significantly bumps minimum browser version requirements for users of apps depending on
+JavaScriptKit. Previous manual memory management mode is still available though with a special
+compiler flags, see [`README.md`](./README.md) for more details.
+
+This new release of JavaScriptKit may work with SwiftWasm 5.4 and 5.3, but is no longer tested with
+those versions due to compatibility issues introduced on macOS by latest versions of Xcode.
+
+Many thanks to [@j-f1](https://github.com/j-f1), [@kateinoigakukun](https://github.com/kateinoigakukun),
