Musl compatible protoc-gen-js

[ghost]

Please provide a musl compatible protoc-gen-js.

I know it's possible because I've been able to build the project in Alpine Linux, but a release tar like the ones we already have for Glibc would be much more convenient. Or maybe a static build that works on both.

In principle, we are not opposed to this, but this work would be blocked on protoc providing build support (likewise for static compilation). It looks like they have a similar issue open here: protocolbuffers/protobuf#7040.

I'll poke the thread to see if they have any updates.
