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.

+Be warned that USE=kernel-open may need to be either enabled or
+disabled for certain cards to function:
+- GTX 50xx (blackwell) and higher are known to require it to be enabled
+- GTX 1650 and higher (pre-blackwell) should work either way
