[TF2] "TF_Map_" strings are not localized in several parts of the game or in Rich Presence

[gaelcoral]

In Simplified Chinese, most map names are localized. However, this localization only appears in the Casual matchmaking map list. In other parts of the game such as the loading screen, mission briefing, scoreboard, and Rich Presence -- the map names still appear in English.

This issue does not occur in CS2.
