Register the LiquidityGauges of the 4 new YB v3 markets (WBTC 0xAa0b1d265F23972eafB7d088e963BD31403A58F5, cbBTC 0xF8764cBcdb15a9E4c7CA1b0b8a578d9ebEEC1b6f, tBTC 0xe83D888FE3213DD3471DE0bC1957E0f94F038483, WETH 0xd829456FD63Ada7DE0657714A3A7A26DE403E3D8) on the GaugeController so they can receive YB emissions. Each add_gauge is guarded by a CallComparator check on the gauge's LP_TOKEN(), so the vote can only execute once the pending market votes have actually created the gauges.
