docs: add written tutorial for new Hedera CYOA tokens demo repo

[bguiz]

Problem

N/A

Solution

• 1st cut of the tutorial text available in the repo already:
  • Task (0) - Set up
  • Task (1) - HTS FungibleCommon Token
  • Task (2) - HSCS ERC20 Token
  • Task (3) - Interoperability between HSCS and HTS
  • Task (4) - Summary and Tear Down
• note that this has been transcribed from video recordings:
  • the technical steps are correct
  • however, the writing style needs to be adapted
• capture screenshots from video, and intersperse within text
• deprecate HFS
  • completed in docs: remove HW for HFS, and redirect it to main HW page #780
