ci: Test bootstrapping configurations with full-ci and on marge batches

There have been two incidents recently where bootstrapping has been
broken by removing support for building with 9.2.*.

The process for bumping the minimum required version starts with bumping
the configure version and then other CI jobs such as the bootstrap jobs
have to be updated. We must not silently bump the minimum required
version.

Now we are running a slimmed down validate pipeline it seems worthwile
to test these bootstrap configurations in the full-ci pipeline.
