Let's add support for running ourcoder CLI on the RISC-V CPU architecture (https://riscv.org/).

It should be relatively straight forward (GOARCH=riscv GOOS=linux) but there's a chance it could be quite involved (topics of stubbing if 3rd party libraries are not supported) thus the importance to communicate early if it looks like this isn't going to be straight forward.

0. buildcoder/coder for RISC-V
1. update our GitHub actions pipelines to publish this RISC-V binary when other binaries for other CPU architectures are published.
2. test your binary on RISC-V hardware.
