ci: tox-lsr 3.16.0 - fix qemu tox test failures - rename to qemu-ansible-core-X-Y [citest_skip]

the latest version of tox 4.49 has a strange issue - it thinks that a tox testenv
like `[qemu-ansible-core-2.20]` is specifying python 2.20 which conflicts with the
testenv basepython of python 3.latest.  There appears to be no way to workaround this.

So, rename all of the testenvs to use `major-minor` instead of `major.minor` e.g.
`[qemu-ansible-core-2-20]`
