Update the role list icons

[Wiglee]

If you view the roles page (https://www.blankmediagames.com/roles/), there are character skins with coordinating roles. However, the list has not been updated, so there are missing skins.

A list of skins that should be on the page, but are not:
- Medusa
- Poisoner
- Hex master
- Coven leader
- Plaguebearer
- Executioner (headsman)
- Hypnotist
- Mafioso
- Consort
- Tracker
- Crusader

This is a small inconsistency that does not have a major impact on the game, but an update would be nice.

Didn't know they did a tracker skin
