### Summary

With 22.04 right around the corner I've been testing some ansible on it to prepare for deploying 22.04 hosts. I've got everything worked out except for adding PPAs.

`apt_repository` is still adding the PPA keys to `/etc/apt/trusted.gpg` instead of placing individual key files in `/etc/apt/trusted.gpg.d/`.

`apt-add-repository` puts the individual key files in `/etc/apt/trusted.gpg.d`.

This move has been ongoing for many years with the previous behavior being deprecated and generating warnings.

### Issue Type

Bug Report

### Component Name

apt_repository

### Ansible Version

```console
$ ansible --version
ansible 2.10.8
  config file = None
  configured module search path = ['/home/wonko/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.10.4 (main, Apr  2 2022, 09:04:19) [GCC 11.2.0]
```


### Configuration

```console
$ ansible-config dump --only-changed
```


### OS / Environment

Ubuntu 22.04 (beta)

### Steps to Reproduce

<!--- Paste example playbooks or commands between quotes below -->
```yaml (paste below)
    - name: Add PPA
      apt_repository:
        repo: ppa:git-core/ppa
        state: present
```


### Expected Results

PPA is added to `/etc/apt/sources.list.d` and gpg key file to be place in `/etc/apt/trusted.gpg.d`

### Actual Results

```console
W: http://ppa.launchpad.net/git-core/ppa/ubuntu/dists/jammy/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
```
