### Summary

Page https://docs.ansible.com/ansible/latest/cli/ansible.html and also `ansible --help` says this:
```
-a <MODULE_ARGS>, --args <MODULE_ARGS>

    module arguments
```
It does not say anything about format <MODULE_ARGS> and thus is not useful to a causal user.

I've learned how to use this parametr only from https://gist.github.com/YumaInaura/06e080e3f807338c122837bdb2d34571

### Issue Type

Documentation Report

### Component Name

https://docs.ansible.com/ansible/latest/cli/ansible.html

### Ansible Version

```console
$ ansible --version
ansible 2.10.8
```


### Configuration

Not applicable.

### Additional Information

BTW I could not find where CLI docs are stored and/or generated, which might potentially help me or other people to submit simple MRs with fixes for similarly simple doc issues. I've looked into https://docs.ansible.com/ansible/latest/dev_guide/index.html and searched for all instances of "doc" but none of occurrences refer to CLI tools.
