Update .goreleaser.yml with Linux riscv64 binaries

[nickolaev]

There are lots of boards with riscv64 architecture available. We can argue if this architecture is more popular accessible than s390x for example. Let's generate the binaries for its Linux OS.

@nickolaev Thanks for the heads up!
K9s does it's best to align with k8s available platforms. Best I can tell, I don't think k8s targets this architecture?

[nickolaev]

Indeed, there is no "support" out of the box. However:

• K9s can be used on a board to manage a cluster remotely, no need to have it locally
• We have a PoC port of KinD that was able to utilize K9s to browse the local resources
• The architecture is gaining more and more popularity and surely will become widely spread at some point

@nickolaev There are some scenarios where k9s shells out and expect kubectl to be present. Eventually we will remove this dependency in k9s core, however lots of plugins expect kubectl and affiliates present on the shell.

Makes sense. Will close it now.
