The "tiers" nomenclature ended up being unhelpful since
we introduced "tier-x" which is between tier-0 and tier-1.
We also never exposed the tier naming outside of our source
code. In preparation for doing so, rename to tier-0 to
"minimal" which is a bit more descriptive.
Renaming the other images will follow.

As agreed in https://gitlab.com/fedora/bootc/tracker/-/issues/39, we're
going to be maintaining the treefile for all Fedora versions in the
`main` branch. Accordingly stop hardcoding releasevers and repos in
the treefiles.
But for now, we're still building the official image in pungi using the
non-container-native path, so add compatibility stubs to not break it.
Coincidentally, this doubles down on the proposed API to build the base
images for different Fedora versions using the `--from` switch. Document
this in the README. But note this doesn't work yet because nothing is
telling rpm-ostree which repos to use or what the releasever should be.
For the same reason FCOS has included it forever; it allows
some skew between images and the RPM mirrors for version-sensitive
things like `kernel-devel`.
