feat: add InGameRoles for teamfortress

[Eetwalt]

Summary

• Add Module:InGameRoles for teamfortress so player classes (scout, soldier, demoman, medic, pyro, heavy, engineer, sniper, spy, pocket) are typed as INGAME by Module:Role/Util.
• Without this, TeamParticipant rendered the class both as a left-side icon (via Module:PositionIcon/data) and as a right-side text badge (since unknown-typed roles fall through to the non-ingame branch in Widget/Participants/Team/Roster).
• Includes the aliases present in the wiki's PositionIcon/data: solly/roamer → soldier, pocketsoldier/pocketsolly → pocket, demo → demoman, engi → engineer, med → medic.

Pull request overview

Adds a Team Fortress–specific Module:InGameRoles data table so TF2 classes (and common aliases) are recognized as INGAME roles by Module:Role/Util, preventing them from being rendered as “unknown” roles (e.g., duplicative text badges alongside position icons).

Changes:

• Introduces lua/wikis/teamfortress/InGameRoles.lua defining TF2 class roles (scout, soldier, demoman, medic, pyro, heavy, engineer, sniper, spy, pocket).
• Adds role aliases matching the wiki’s PositionIcon/data naming (e.g., solly/roamer → soldier, demo → demoman, etc.).
