v2.7.0 to v2.11.12

Python version

Steps to Reproduce

install python3 somewhere other than /usr/bin/python3

Observed Behavior

]# ./upgrade.sh
Creating a new virtual environment at /var/lib/netbox-2.7.12/venv...
./upgrade.sh: line 20: /usr/bin/python3: No such file or directory
--------------------------------------------------------------------
ERROR: Failed to create the virtual environment. Check that you have
the required system packages installed and the following path is
writable: /var/lib/netbox-2.7.12/venv
--------------------------------------------------------------------

IIRC, we specify the full path to ensure that the system Python executable is used, rather the one from a virtual environment that might happen to be active. I'm not sure this really matters, though.
