Add One platform to the list

Hello,

I would like to suggest adding [Cybertalents](https://cybertalents.com) to the list of platforms.

a well known website hosting jeopardy style challenges for many categories "Forensics/RE/Crypto/Web,..." also providing a monthly regional CTF events would be useful for practicing

Start by locating the repository's platform list and review the Cybertalents site linked in the issue. Done means the Cybertalents link is added to the appropriate list entry with an accurate description and category, without disrupting the existing formatting.

Written by the indexing model from the issue text.
