-->
<!-- Describe your changes here in detail -->

<!-- Why is this change required? What problem does it solve? -->
On `centos-7`, still supported until June 2024, we have to use sage-
bootstrap-python = python2.
Support for Python 2 was broken accidentally in sagemath#36393, see https://gith
ub.com/sagemath/sage/actions/runs/6520548150/job/17767608828#step:10:192

Fixed here, as tested with `tox -e docker-centos-7-devtoolset-
gcc_11-standard -- config.status`.

Same issue also affects `fedora-30`, which is still tested by the CI as
a proxy for old RHEL, and `ubuntu-xenial`. See sagemath#32074
