Removing "track" tau trigger type
"track" tau trigger was used to validate the 2 stage FTF-tracking in the tau trigger during and it was never used for physics. Therefore we believe it could be deleted for the menu and from tau trigger since all tau trigger tests mainly focusing on chains with 2-stage tracking.
tagging @iriu and @carquin from tau trigger side
tagging also @jmasik and @sutt and asking if it's fine to remove this chain type or is still use somewhere for validation
