chore: use GHCR for install.sh (#11)

Trying to make the action install the binary from the container on GHCR
with `podman run --rm ghcr.io/blue-build/cli:main-installer | sudo bash`
(like in the README). Getting some error and this _might_ be related and
might not, but shouldn't hurt to merge either, since I just made the
`cli` package public.
