"Python 2 is deprecated. Upgrade to Python 3 as soon as possible." message when upgrading gyb

[jay-eleven]

The install script install-gyb.sh checks for Python2 BEFORE Python3 so a "Python 2 is deprecated" message is shown in Google Cloud Shell that has both versions installed.

I think swapping lines 178 and 182 (ie. checking for Python 3 first) would solve this issue... 🤔

This is the complete upgrade sequence plus a couple of checks:

jay@cloudshell:~$ cat updategyb.sh
bash <(curl -s -S -L https://git.io/gyb-install) -l

jay@cloudshell:~$ ./updategyb.sh
