jinja2.contextfilter decorator renamed to pass_context

[mdz]

Proposed change

Bump jinja 2 from >= 2.11.3 to >= 3.0.1
jinja2 release notes: https://jinja.palletsprojects.com/en/3.0.x/changes/#version-3-0-1

Fix this warning:

homeassistant/helpers/template.py:1319: DeprecationWarning: 'contextfilter' is renamed to 'pass_context', the old name will be removed in Jinja 3.1.

Since this was added in Jinja 3.0.1, bump the dependency accordingly. This is the same version we actually get in practice when all of the dependencies are installed, so this doesn't change the version in use in practice.

$ docker run homeassistant/home-assistant:stable pip3 show jinja2
Name: Jinja2
Version: 3.0.1
Summary: A very fast and expressive template engine.

It's correct that a fresh install will get Jinja2 3.0.1 since we don't pin the version:

jinja2>=2.11.3
