fix(tools): support NVIDIA driver versions with 2 segments (xxx.xxx)

The regex for parsing the NVIDIA host driver version from
/proc/driver/nvidia/version required 3 version segments (xxx.xxx.xx)
but newer drivers like 580.142 only have 2 segments. Made the third
segment optional with (\.\d+)? to match both patterns.

Closes #12784
