Merge #16139: Docs: Add riscv64 to outputs list in release-process.md

6f7f141 Add riscv64 to outputs list in release-process.md (JeremyRand)

Pull request description:

  The `riscv64` binary is created by the Gitian scripts and distributed by the Bitcoin Core website, so it should be listed in the release process docs.

  I placed it between i686 and x86_64 since it looked like the original list of Linux arches was in alphabetical order; I'm open to including it in a different position if the desire is to keep the two ARM arches together and the two x86 arches together.
