Add variable to "forcefully" enable/disable deb822 format

 Controls whether this role will add the official Docker repository. Set to `false` if you want to use the default docker packages for your system or manage the package repository on your own.
 
+For any instance running Ubuntu 24.04 or later, the Docker repository source file will be in `deb822` format by default.
+
+This behavior can be modified using the `docker_deb822_format` variable. For example, if the one-line format is preferred, set the variable as follows:
+
+```yaml
+docker_deb822_format: false
+```
+
+When set to `true`, the `deb822` format will be used for all Debian-based installations. Note that enabling this will also remove any existing `docker.list` file and install `python3-debian`.

 docker_repo_url: https://download.docker.com/linux
