Update deprecated cuda import

[lochhh]

Closes #4110

This PR also pins the minimum cuda-python version to 11.8.6

Note

The new module layouts were applied in 11.8.4, but I was getting:

Could not find a version that satisfies the requirement cuda-python==11.8.4; platform_system != "Darwin" and extra == "full" (from spikeinterface[full]) (from versions: 11.8.6, 11.8.7, 12.8.0, 12.9.0, 12.9.1, 12.9.2, 13.0.0, 13.0.1)

Thanks all for the speedy review. Great point regarding pinning - I've pinned it to >=11.8.6 and added some notes above.
