Update conditional in project update playbook - require min Ansible 2.9 to install collections

SUMMARY

This needs to be backed off from 2.8 to 2.9:

awx/awx/playbooks/project_update.yml

Line 165 in 7082448

- "ansible_version.full is version_compare('2.8', '>=')"

Because if you run with Ansible 2.8, it gives blank stdout and that's confusing.

If my research is correct, @jborean93 added the ansible-galaxy collection CLI in ansible/ansible#57106, which was 2.9. Version 2.8 seems to mistake these invocations for a role command, and it doesn't work right.

This is done, now collections will only be installed if ansible running the project update is >= 2.9

We might also want to change some conditional skips in tower-qa, because the reason we saw this was because some tests were failing unexpectedly in 2.8. Best approach may be just to run tests with 2.8 and see what happens.
