refactor: soften up application message

There is currently the following message displayed in an embed to those
who make use of the `/application-form` slash command:

    We are always looking for community members that want to contribute
    to our community and take charge. If you are interested, you can
    apply for various positions here!

This is too hardened and serious according to feedback. Add a smiley
face in the form of a cool sunglasses emoji to soften it up.
