fix: Python version check for PyTorch installation compatibility

[ochen1]

Description

you cannot use An arbitrary precision calculator language to compare python versions

eg. bc will think 3.10 and 3.1 are the same

As such, we must update the script to maintain a consistent two-decimal format for comparison by modifying the version calculation to ensure that the minor version is always represented with two decimal places.

Screenshots/videos:

pyv="$(${python_cmd} -c 'import sys; print(".".join(map(str, sys.version_info[0:2])))')"
if [[ $(bc <<< "$pyv <= 3.10") -eq 1 ]] 
then
    # Navi users will still use torch 1.13 because 2.0 does not seem to work.
    export TORCH_COMMAND="pip install --pre torch torchvision --index-url https://download.pytorch.org/whl/nightly/rocm5.6"
else
    printf "\e[1m\e[31mERROR: RX 5000 series GPUs must be using at max python 3.10, aborting...\e[0m"
    exit 1
fi
