Replace "contributos" with "creators"

[lnxpy]

Just to remove the "Contributors" section and replace it with "Creators" and add the legit creators' profile avatars with a simple bio with social links. These tasks need to be done!

• [ ] - Replace the contributions with creators (most probably big avatars with a short bios and socials)
• [ ] - Remove the cron command for re-generating contributor.svg file since contrib.rocks (the service that generates the images) is blocked from the webserver.
