Change the test manifests that use containers to not include
docs when installing. Also don't install docs in the build root
for those manifests. Since the fedora-ostree-container.mpp is
being built in CI, this also tests that the new option.
Add an example that builds a small container, based on the minimal
container fedora kickstart (see [1, 2]). There is a deviation
because osbuild currently does not support removing
random files like it is done in [2].
The build pipeline "build" in f32-build-v2.json) is a port of the
existing build pipeline in f32-build.json.
This manifest is currently not used in any automated tests (yet),
but is there as a showcase for the new format. It does however
test the format version 2 support for mpp, since that is called
in CI.
