Keep image up-to-date with its components [NVIDIA drivers]

[pavlovic-ivan]

Describe the improvement request

NVIDIA drivers should be kept up-to-date in the image.

I think that a daily scheduled workflow could be used to check for updates of NVIDIA drivers, and create a PR with the new version number set in variables.auto.pkrvars.hcl when an update is detected. We may also want to have a workflow running on PRs that builds and tests the image, but does not save it.

The decision to go from one major version to another should be done by a human (e.g. by updating the scheduled workflow).
The latest datacenter driver versions can be found on https://docs.nvidia.com/datacenter/tesla/index.html. We should probably parse this HTML file (e.g. with https://pypi.org/project/beautifulsoup4/ or https://developer.mozilla.org/en-US/docs/Web/API/DOMParser/parseFromString) and figure out the latest version for a given major (e.g. 470 -> 470.103.01 at the time of writing).
