x11-drivers/nvidia-drivers: update readme/metadata for blackwell
Several reports on NVIDIA's forums (and some old news posts) point
to requiring the open variant for blackwell, not that it's something
I've verified myself.
In the future may possibly try to implement a postinst check to verify
if usage of USE=kernel-open is correct. Currently the .json file has
a 'kernelopen" to know if it's usable but does not say whether it's
required or not for blackwell at the moment.
May also need to consider making USE=kernel-open default eventually,
albeit that could potentially wait until non-GSP cards are tossed in
a legacy branch then the new branch could be kernel-open-only.
