Bump python 396 (singer-io#130)

* Update psycopg2 to a version that supports python 3.9.6

* Use python 3.9.6 to build the tap's virtualenv

* updated tap-tester image

* Install libpq-dev before we install psycopg2

* psycopg2==2.9.1 has a change we don't want

* Install psycopg for tap-tester

* revert docker image as tap tester is now on 18.04
