Add Poseidon as type

[MMorokk]

Enhancement Type

New server type

Describe the enhancement

Poseidon is a fork of bukkit for minecraft b1.7.3. Seems cool enough to add, and im interested in running it.

Please just use https://docker-minecraft-server.readthedocs.io/en/latest/types-and-platforms/server-types/others/#custom for that.

I have very limited time and energy to support these projects, so honestly adding a server type derived from a very very old Minecraft version seems impractical.

Ah, from your other issue I was reminded that Canyon is only b1.7.3 😀

So, another server type similar in lineage is reasonable.
