Create your own channels

• This took a surprisingly long time to implement (Tailwind and Framer
  Motion are really annoying), but I finally made a channel creation
  feature where you can create your own chat channels on Codeliver
• When you hover over the Channels category on the left chat sidebar,
  you’ll see a menu button option that appears, and when you click on it,
  it opens a channel management menu
• You can choose to either create a channel, browse/search for available
  channels to join (not implemented yet), or click away to close the menu
• If you choose create a channel, a modal will pop up where you can put
  its name (must be unique and made of lowercase characters and dashes),
  description, and set its visibility with the cool toggle
• If you create the new channel successfully, you’ll be automatically
  redirected to it where you can start chatting in it!
• The browse channels options currently just shows an empty modal with a
  search bar that doesn’t do anything yet
• Updated schema and types for channels and messages
• Updated styling and navigation
