Cannot install in projects using httpx 0.24.1

[codenaz]

This library requires you to use httpx 0.23.3 in your project. Installing a project that already has a higher version (in my case 0.24.1) will result in the following error.

Dependency manager: poetry 1.6.1
Python version: 3.11.0
Framework/Library: Fast API 0.101.1

Because no versions of pact-python match >2.0.1,<3.0.0
 and pact-python (2.0.1) depends on httpx (0.23.3), pact-python (>=2.0.1,<3.0.0) requires httpx (0.23.3).
So, because `project_name` depends on both httpx (^0.24.1) and pact-python (^2.0.1), version solving failed.

To reproduce:

in pyproject.toml

httpx = "^0.24.1"

poetry install
poetry add pact-python

I closed #388. #371 will address this
