Issue:
community.general.flatpak module isn't idempotent when installing packages
### Summary

I'm trying to install a list of flatpaks

`roles/05_packages/tasks/flatpak.yml`

```
---
- name: Add Flathub repository
  community.general.flatpak_remote:
    name: flathub
    state: present
    flatpakrepo_url: https://flathub.org/repo/flathub.flatpakrepo
  become: true

- name: Install flatpaks
  community.general.flatpak:
    name: "{{ flatpaks }}"
    state: present
    remote: flathub
```

`group_vars/all.yml`

```
flatpaks:
  - com.discordapp.Discord
  - com.github.tchx84.Flatseal
  - com.slack.Slack
  - com.spotify.Client
  - com.valvesoftware.Steam
  - com.valvesoftware.Steam.CompatibilityTool.Proton
  - org.gtk.Gtk3theme.Adwaita-dark
  - org.gtk.Gtk3theme.Yaru-dark
  - org.gtk.Gtk3theme.Yaru-light
  - us.zoom.Zoom
```

I get the following error on `Install flatpaks` (with `-vvvv`) and the step isn't idempotent:

```

I think the error is in [plugins/modules/flatpak.py](https://github.com/ansible-collections/community.general/blob/main/plugins/modules/flatpak.py) line 218 the "--app" option.
"org.gtk.Gtk3theme.*" is NO app.
