🧑‍💻 Set up the package's CLI for adding commands

[paduszyk]

Description

This configures the package's command-line interface using click.

In particular, the CLI is set up for adding commands. They can be defined in the gitmojis.cli.commands module to be then automatically registered in the main CLI hook.

Finally, the CLI is added to the package's entry points/scripts.
