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]` Signed-off-by: Rich Megginson <rmeggins@redhat.com>
