Remove game-related vocabulary to stay compatible with pro conferences

[asaurat]

Minotaure can be used in many contexts, not only RPGs.
Removing (or making optional) game related terms could facilitate adoption by speakers (Education might be a field interested in this kind of tool).

I took the liberty of assigning the ticket to you. You can find all text used in https://github.com/uurshin/minotaure/blob/main/src/locales . If you can list the ones you find too "rpg focused" and better alternatives it would be nice.
