Add private key password reset instruction in - https://docs.hpc.ucdavis.edu/general/troubleshooting/

Some users ask about how to reset the private key password, can we add this in the troubleshooting part for SSH key pair?

Command to reset private key password - only if you know the old password

ssh-keygen -p -f /root/.ssh/id_rsa

That makes sense to me. Please create a branch and add this. Then create a PR and ask for it to be reviewed.
