Add Xkonti's livestreams to "Videos" section

[Xkonti]

A series of livestreams documenting the learning process of SurrealDB with focus on SurrealQL. The SurrealDB staff and discord members occasionaly help out and clear things up.

The series is still ongoing and will focus on implementing a non-trivial database solution that allows people to comment like and mark things as learned on a personal blog website.
