Add entities list to lookup.py

Add list of entities present in Minecraft 1.19.2, sourced from https://github.com/PrismarineJS/minecraft-data/blob/master/data/pc/1.19.2/entities.json

This does seem useful, but I'm not sure if we should include it in GDPC for the same reason as in #83 (comment) (I'm careful about all additions that require permanent maintenance). Python-minecraft-data (https://github.com/SpockBotMC/python-minecraft-data) already provides to all PrismarineJS data, and seems maintained well enough. Is there any particular advantage to including this in GDPC directly?

[Niels-NTG]

To be honest I forgot this existed as a Python package.

Having re-learned this now I admit there isn't really an advantage to including this data here directly. I do think that instead it could be beneficial to create a wrapper and/or util functions in gdpc that make use of this package such that lookup.py in its current form can be replaced.

Adding wrappers for some common lists does indeed sound like a good idea! I've opened #89 for it.
