Subject: [PATCH] ci: Regenerate the initramfs after installing bootc from copr

The CI image replaces the base image's bootc with a newer build from
copr but keeps the base image's initramfs, which bootc doesn't support.
It broke the stream10 composefs UEFI boot test once bootc started
writing only composefs.digest= in BLS entries: the bootc 1.16.13
initramfs in centos-bootc:stream10 only starts bootc-root-setup.service
with a composefs= karg, so switch-root fails.
