Fedora Design Team Docs: Revamp Portfolio / Previous Work 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 Portfolio / Pervious Work section will say. This just needs to be a text draft for now and some graphics to include to show off our previous work.

Some points and subheadings to include:

Portfolio / previous work

Wallpapers

• Most recent release cycles

Logos

• Logos recently created - maybe within the last year.

Printed materials (Stickers, flyers)

• Printed materials recently created - maybe within the last year, such as at Flock or events.
