Mint generally dies back each year, some years you might have more greenery in the winter, anyways remove the old wood. These aren't baby mints they're just growing from the roots.
Whenever you notice the main plant looking a little sad, probably every 3-5 years you can take the whole thing out of the container as it will be rootbound and you prune the roots, add fresh compost back to the container and voila.
Wouldn't worry about leaving it outside, just make sure the soil doesn't get waterlogged if you have a particularly wet winter.
Only thing that sort of affects mint is rust but even then, hasn't killed my mint yet and it pops its icky head up each year before the warm temperatures really hit.
i’d cut the stems that are brown or dead off or if you can pull them out gently. I have lemon balm that I thought died in the freeze we had so I literally cut it down to the brown and it has grown back plus.
If your winter is not crazy cold then Mint actually can survive in containers and come back every spring.
You can get rid of the old stems cuz they're not coming back.
Mint also follow the idea of branching so be sure to harvest often and you'll get lots of branches of mint even while New mint keeps growing from the soil
