[PATCH 5.15 042/913] docs: sphinx/requirements: Limit jinja2<3.1

[Greg Kroah-Hartman]

From: Akira Yokosawa <akiyks@xxxxxxxxx>

commit be78837ca3c88eebd405103a7a2ce891c466b0db upstream.

jinja2 release 3.1.0 (March 24, 2022) broke Sphinx<4.0.
This looks like the result of deprecating Python 3.6.
It has been tested against Sphinx 4.3.0 and later.

Setting an upper limit of <3.1 to junja2 can unbreak Sphinx<4.0
including Sphinx 2.4.4.
