ci: Add supported_ansible_also to .ansible-lint

This fixes the breakage of ansible-test.

We want to advertise support for ansible 2.14 since some of
our collections will be supported for a long time on this
version.  The latest version of ansible-lint requires 2.15
in meta/runtime.yml, but it also adds support for a way to
tell ansible-lint other versions which are acceptable, using
the new `supported_ansible_also` configuration option
in .ansible-lint

With this fix, we can support both the latest version of
ansible-test and ansible-lint.

See linux-system-roles/auto-maintenance#341
for more information.
