upstream CI: Enable tests using ansible-core 2.12.

As the current latest upstream version of ansible-core is 2.13.0, to
test against ansible-core 2.12 series we need to pin the version used
on the test.

This patch enables the already defined tests for ansible-core 2.12 that
were available but commented out.
