If a galaxy requirements file contains collections that have signatures defined, then `ansible-galaxy role install` with that requirements file fails because a keyring is not supplied.

### Issue Type

Bug Report

### Component Name

ansible-galaxy

### Ansible Version

```console
$ ansible --version

ansible [core 2.13.0.dev0] (devel ff184b0815) last updated 2022/03/24 16:21:31 (GMT -400)
  config file = /home/shrews/.ansible.cfg
  configured module search path = ['/home/shrews/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/shrews/Devel/github/Shrews/ansible/lib/ansible
  ansible collection location = /home/shrews/.ansible/collections:/usr/share/ansible/collections
  executable location = /home/shrews/Devel/github/Shrews/ansible/bin/ansible
  python version = 3.9.7 (default, Sep 10 2021, 14:59:43) [GCC 11.2.0]
  jinja version = 3.1.0
  libyaml = True
```

```


### OS / Environment

### Steps to Reproduce

<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)

$ cat req.yml 
collections:
  - name: community.mysql
    signatures:
      - file:///home/shrews/test.asc

$ ansible-galaxy role install -r req.yml 
ERROR! Signatures were provided to verify community.mysql but no keyring was configured.
```


### Expected Results
