Reason: Same artist, see their profiles.

EDIT: The tag alias vennightsky -> vensicle (forum #325900) has been approved by @bitWolfy.

Vensicle IB has links to the vennightsky FA etc. Also the venchizu Twitter His various names all seem to have been last updated October 2020.

I vote for aliasing to ven_chizu, since that's his signature. Something like

alias vensicle -> ven_chizu
alias venchizu -> ven_chizu
alias vennightsky -> ven_chizu.

The artist seems to prefer vensicle, so I think we can go with that one.
It's also their Discord and Pixiv username, as well as the Twitter display name.
