Remove Ansible for IBM Z

You may want to remove an IBM Ansible for Z collection for various reasons, for example, you installed the collection into the host and wanted it installed in a Python virtual environment.

To remove a collection, navigate to the collection directory and remove the collection by using this command:
```
rm -rf <path_to_collection_directory>/<collection name>
```
If you you do not know where the collection is installed, you can use the ansible-galaxy command to show the installation path for a specific collection with command:
```
ansible-galaxy collection list ibm.ibm_zos_core
```
Verify the uninstallation by running this command:
```
ansible-galaxy collection list
```
