Issue with Jinja2 v3.1.1

[mvadari]

Describe the bug

I'm trying to set up Sphinx in a new repo and I'm running into an error with Jinja2. It errors when I use Jinja2 v3.1.1, but is fine with v3.0.3.

$ poetry run sphinx-apidoc -o source/ ../folder
Traceback (most recent call last):
  File "/Users/mvadari/Documents/folder/.venv/bin/sphinx-apidoc", line 5, in <module>
    from sphinx.ext.apidoc import main

ImportError: cannot import name 'contextfunction' from 'jinja2' (/Users/mvadari/Documents/sidechain-launch-kit/.venv/lib/python3.8/site-packages/jinja2/__init__.py)

How to Reproduce

Upgrade Jinja2 to 3.1.1, and attempt to run sphinx-apidoc.

Expected behavior

I expected the Sphinx .rst docs to generate properly, but instead there was an error.

This is also affecting numpydoc and scipy (scipy/scipy#15895), albeit with older sphinx versions (2.1)

[mvadari]

My solution was to upgrade Sphinx to 4.5.0.

This is a duplicate of #10291, you can update sphinx to the latest version or pin Jinja2 Jinja2<3.1 in your dependencies.
