DeprecationWarning: 'contextfilter' is renamed to 'pass_context'

nbconvert/nbconvert/exporters/html.py

Line 14 in d7c286b

from jinja2 import contextfilter

As discussed here: pallets/jinja#1381
contextfilter is now deprecated.

This causes the following warning to show up whenever using the exporters:

...
/opt/hostedtoolcache/Python/3.9.5/x64/lib/python3.9/site-packages/nbconvert/exporters/html.py:100: in HTMLExporter
    def markdown2html(self, context, source):
/opt/hostedtoolcache/Python/3.9.5/x64/lib/python3.9/site-packages/jinja2/filters.py:54: in contextfilter
    warnings.warn(
E   DeprecationWarning: 'contextfilter' is renamed to 'pass_context', the old name will be removed in Jinja 3.1.

Thanks

This should presumably have been fixed in #1624

Hi, I am still getting this warning with nbconvert. Version: 6.1.0

Is there a way to resolve?

contextfilter is removed in the current jinja2 version, 3.1.1, on PyPI.
So fixing this is getting urgent.
