Updation required in the instructions for installing cuda toolkit 12.1 in Ubuntu

[PriyajeetGoswami]

The instructions for Cuda Toolkit 12.1 is wrong on this page(https://developer.nvidia.com/cuda-12-1-0-download-archive?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=deb_network) for target os: Linux, distro: Ubuntu, x86 architecture.

The network based installer doesn't explicitly mention which cuda version to install, hence it installs the latest version which 12.6 now. The local and runtime installer installs cuda 12.1 for driver version 530 only. Please modify the instruction commands, so that others don't face the issues during downloading and installing cuda toolkit 12.1 on Ubuntu.
