remove Danger Science section

[wdhdev]

Reasons for removal:

• No active SSL certificates on fwnk.site or folionetwork.site: https://crt.sh/?q=fnwk.site&exclude=expired https://crt.sh/?q=folionetwork.site&exclude=expired
• Very few active SSL certificates found on platform0.app: https://crt.sh/?q=platform0.app&exclude=expired
  • I believe they may issue SSLs on a per domain basis, and only use wildcards on the occasion where no website exists using a wildcard (e.g. https://exampletest123.platform0.app)
• In the original PR Add Danger Science Group domains #1074, the domains fwnk.site and folionetwork.site were intended to be used by https://folio.network, however the domain does not have any A/AAAA records, therefore it doesn't resolve.
• No results on Google or Bing for any of the domains when searching using site:{domain}.
• _psl.fwnk.site is missing, however for the other 2 domains it is still in place.

It is evident that fwnk.site and folionetwork.site are not in use any more. platform0.app does appear to get an extremely small amount of use, however it is nowhere near our threshold for inclusion and should be removed. I think these domains can be safely removed.
