Add support for prerotate script (#22)

[danrough]

---

name: Add prerotate
about: logrotate allows for a user to specify a script that can be run before the rotate process runs. This change adds that functionality to this role.

---

Describe the change
I've copied the postrotate feature, and its tests, and duplicated it as prerotate.

Testing
Unfortunately, despite my efforts, I haven't been able to get molecule running with docker locally, and so I haven't been able to run the tests. It seems that docker-py 2.32.0 / requests has a an issue with ansible 9.6. I've tried upgrading to ansible 10.0.0b1, but I still haven't been able to get it to work.

Just wanted to update to say that I have continued trying to get molecule working with the docker driver, and that I am still stuck. I posted a request for help regarding my problems with molecule on the ansible forum, you'll find it here: https://forum.ansible.com/t/critical-driver-docker-from-state-file-users-myusername-cache-molecule-ansible-role-logrotate-default-state-yml-is-not-available/5979

Looks good, let's wait for CI.

I'll change converge.yml after merging to include a generic example and a pre-rotate example. (Since that's being tested as well.)

I wonder if the failures in these tests related to this bug, ansible-community/molecule-plugins#256

[danrough]

@robertdebock I've just linked an issue that was found yesterday in molecule-plugins - I'm wondering if that might be the cause of these test failures. Sadly, despite my best efforts, I still can't get molecule working on my machine. Proof, if you need it that I am still trying is here on Reddit, and here on the ansible forum.

I've pushed a fix for the duplicate files issue.
