Requirements: revert upgrade to `psycopg==3.x` (#10713)
* Requirements: revert upgrade to `psycopg==3.x`
This package works fine and the upgrade was transparent. However, it seems that
New Relic agent is not prepared to collect data from v3.x and send it to their
servers.

`psycopg3` is compatible with DB-API 2.0, but for some reason doesn't work.
I'm reverting it for now and we can take a look later.
Note this commit also upgrades Django, due to a security issue that was
reported:
