Fix to quickyaltaiinstall.sh if virtualenv is not installed

[alix-tz]

I was getting the following error when executing quickyaltaiinstall.sh

./quickyaltaiinstall.sh: line 1: virtualenv: command not found
./quickyaltaiinstall.sh: line 2: yaltaienv/bin/pip: No such file or directory
./quickyaltaiinstall.sh: line 4: virtualenv: command not found
./quickyaltaiinstall.sh: line 5: krakenv/bin/pip: No such file or directory

python3.10 -m venv can be used as an alternative to virtualenv -p python3.10.
