Before this change we were using psycopg 2.9.10. This does not seem to be designed to [work correctly with gevent](https://www.psycopg.org/docs/advanced.html#support-for-coroutine-libraries) "out of the box". The [psycogreen](https://github.com/psycopg/psycogreen/) library was written to resolve that problem but we don't seem to be using it at all. Upgrading to [psycopg 3 allows proper integration with gevent](https://www.psycopg.org/psycopg3/docs/advanced/async.html#gevent-support) without psycogreen or other workaround. This change upgrades service-stac from psycopg 2.9.10 to 3.2.9. This was done by updating the Pipfile then running `pipenv install`. This also updated other dependencies. In local tests, I verified the `/checker` endpoint remains much more responsive with this change when end-to-end tests are being run. Maximum measured latency dropped from ~15 seconds to ~3 seconds.
PB-1785: upgrade to psycopg 3.
