README: Mention Python 3 support

Also, since Ansible 2.5 is the first release to fully support Python
3-only targets, make that the minimum requirement.

### Python 3
All of Taiga runs on Python 3, and [since Ansible 2.5 and later fully
support Python
3](https://docs.ansible.com/ansible/latest/reference_appendices/python_3_support.html),
the roles in this repository should allow you to build completely
“Python 2-free” systems.
However, the `rabbitmq-server` package in Ubuntu Bionic [currently has
a dependency](https://packages.ubuntu.com/bionic/rabbitmq-server) on
`python` (the Ubuntu Python 2 package). Thus, if you run with
`taiga_enable_events: true` and/or `taiga_enable_async_tasks: true`,
which will install `rabbitmq-server` onto your `taiga-back` and
`taiga-events` nodes, you will pull Python 2 libraries into those
systems. This — [depending on your Ansible
configuration](https://docs.ansible.com/ansible/2.8/reference_appendices/interpreter_discovery.html)
— may or may not cause Ansible to revert to Python 2 on subsequent
runs.
