[Merge] ~codyshepherd/livecd-rootfs/+git/livecd-rootfs:fix/riscv64-manifest-gen into livecd-rootfs:ubuntu/jammy

[Simon Poirier]

pro-tip: You want to tidy/squash the git history for packages changes.

I generally try to keep everything in 1 commit, and have a separate one with the debian/changelog update.
This keeps everything clear and make porting a specific change between suites easier.
