Fedora Design Team Docs: Revamp Introduction / About section

As part of &13 we are revamping https://docs.fedoraproject.org/en-US/design/ to include more information and make it look more inviting 😃 taking inspiration from our old Wiki page: https://fedoraproject.org/wiki/Design. We are going to break it down into sections and work on one part at a time.

Tickets for other sections can be found in the Fedora Team Resources epic: &13

For this ticket, we need to have what our About Us / Introduction section will say. This just needs to be a text draft for now.

Some points and subheadings to include:

About Us

Introduction for (active) Design team members

• a list and small introduction to current members

Social contract

• Fedora Code of Conduct
• Social norms within Fedora Design

Acknowledgements

• The different artwork styles are determined by the individual artist

Roles

• "You don't have to be an artist to join the Design Team," e.g., moderator, communications, docs, general feedback, etc
