Build OSTree commit using component

When installing Debian packages, apt-ostree can reference packages
from an specific component. Each component is related to a patch
version (sw_release).

Test Plan:
PASS Install apt-ostree from git repo.
PASS Run "apt-ostree compose create \
--base config/debian/bookworm \
--repo /repo debian/bookworm \
bookworm-test"
PASS Run "apt-ostree compose install --repo /repo \
--branch bookworm-test --component <sw_release> docker.io"
PASS Check the output of "ostree log --repo /repo bookworm-test"
