Fix Body Preset Feminine Fat

The other feminine body presets all select the female gender but the fat preset does not. This means if you are transitioning someone AMAB in to a chubby girl their gender will be set wrong unless you catch it. This addresses that issue by setting the gender to female like the other feminine body presets. This is only needed until the devs patch the game and fix this issue. Something easily worked around like this isn't typically a high priority.
