nix: fix shadow-cljs on M1 by upgrading to 2.11.16

On M1 calling `shadow-cljs` fails with:
```
Execution error (UnsatisfiedLinkError) at java.lang.ClassLoader$NativeLibrary/load (ClassLoader.java:-2).

            (fat file, but missing compatible architecture (have (unknown,i386,x86_64), need (arm64e)))
```
This is due to an outdeted dependency on JNA 3.2.2, which is pulled in
by `hawk` package which up until release `2.11.16` was a `shadow-clj`
dependency which was removed because it was:

>Only used to be used on macOS since it was slightly faster than the default
>JVM implementation. However in Big Sur it seems to cause issues and break
>completely or just be a lot slower.

thheller/shadow-cljs@f3b89b5a

Dropped the explicit dependency on `org.clojure/core.async` to avoid:
```
WARNING: The org.clojure/core.async dependency in shadow-cljs.edn was ignored.
Default version is used and override is not allowed to ensure compatibility.
```

Resolves: #14196
