WSL error for installation

PS C:\harness> wsl --status
Default Distribution: Ubuntu
Default Version: 2
PS C:\harness>

Command: curl -fsSL https://raw.githubusercontent.com/harness/cli/main/install.sh | sh

Error: curl: (60) SSL certificate problem: self-signed certificate in certificate chain

This looks like an enterprise SSL cert that wasn't correctly installed for the WSL sub-system (as this is a curl issue against github, before we even get to our install script).

I added a set of manual instructions for installing from the tar.gz files:
