Dynamic Detection of Nvidia driver

### Comment:

We presently detect the version of the nvidia driver at installation time.

That isn't always the best, and ideally we could detect it at runtime.

See https://github.com/conda-forge/ffmpeg-feedstock/issues/288#issuecomment-2833665419 as to why that is difficult.

However, it is still desirable.

Start by reading the linked ffmpeg-feedstock issue comment to understand why runtime Nvidia driver detection is difficult, then inspect how this feedstock currently detects the driver version during installation. Done means the driver version is detected at runtime instead, with the existing installation-time limitation addressed.
