Describe the issue
When I ran the command "ansible-galaxy collection install git+https://github.com/confluentinc/cp-ansible.git", I got a error msg as below

ansible-galaxy collection install git+https://github.com/confluentinc/cp-ansible.git
Process install dependency map
ERROR! Invalid collection name 'git+https', name must be in the format .. Please make sure namespace and collection name contains characters from [a-zA-Z0-9_] only.

If i only use "https://github.com/confluentinc/cp-ansible.git", I got: ERROR! Collection artifact at '/root/.ansible/tmp/ansible-local-2769zjh1df7g/tmpdoh5uhch/cp-ansible5yjnh9za.git' is not a valid tar file.

So that, I cloned by the cmd " git clone https://github.com/confluentinc/cp-ansible". After that, I run "ansible-playbook -i hosts.yml confluent.platform.all", the problem is "ERROR! the playbook: confluent.platform.all could not be found"
