Use subshells for installation and upgrade instructions

Browse Source 
I recently upgraded my copy of nvm and I was disappointed to be dropped
in the .nvm directory at the end of it. I also didn't like having to
copy and paste two separate blocks of code into my terminal, because I
missed the second one the first time around and was left in a slightly
confusing state. So, I decided to make this easier by utilizing
subshells and moving all of the instructions into one code block in this
document. I think this will improve people's experience maintaining this
tool.
