Support Dedicated Server Platform

[PhiSel]

Since Unity 2021.2, Unity provides a new platform target "Dedicated Server".

It would be great to use this target instead of "linux server build."

Thanks for the suggestion, @PhiSel! This sounds like a good idea, I've added it to the backlog.

Aw man.. I just found this awesome project to ease my pain of "Switch Platform" when building my client and server - only to see this ticket.

Big upvote for this <3
