Add footer contact details

[wizardlink]

Information

This footer section should be "grid" (actual grid or flex) based, having three columns:

1. Contact information (Left corner)
   • E-mail
   • Discord server (hydractify.org/discord)
   • Twitter
2. Empty column
   • "Empty" for potential eventual usage. Currently existing to create a wide gap between the leftmost and rightmost column.
3. Relevant links (Right corner)
   • GitHub
   • Patreon
   • Steam

All icons should already exist with antd, so you can just use that.
