Dependency issue: Minimum ijson version to low preventing to join rooms

[passw0rd123]

Description

Usage of use_float in ijson introduced in e81fa92 needs a minimum version of 3.1

Set version "ijson>=3.0" in https://github.com/matrix-org/synapse/blob/develop/synapse/python_dependencies.py is to low. use_float is introduced in ijson 3.1

Joining rooms is failing with the following error.

Failed to join room
