Use a more appropriate example for role menu creation

[FlareLine]

Hey there,

Currently, the YAGPDB docs currently use Gender as an example for role menu creation. I propose that we use a friendlier example such as Fruits or Colours.

See https://github.com/botlabs-gg/yagpdb-docs/blob/986ed644e74225a93fdb26111db0b66a8d5d871f/tools-and-utilities/self-assignable-roles.md#step-by-step-tutorial

Keen to see what anyone else thinks.

Any update on this?
