Pypi mkdocstrings 0.15.0 has dependency constrain Jinja2 < 3.0

[lyz-code]

I'm encountering an error when updating the dependencies of one of my projects with pip-compile due to the dependency constrain Jinja2 < 3.0.

To Reproduce
Steps to reproduce the behavior:

1. Clone the repo: git clone https://github.com/lyz-code/mkdocs-newsletter/
2. cd mkdocs-newsletter
3. Edit the first line of docs/requirements.in from -r requirements.txt to -r ../requirements.txt
4. make update
5. See error

  Jinja2<3.0,>=2.11 (from mkdocstrings==0.15.0->-r docs/requirements.in (line 11))

Expected behavior
pip-compile correctly updates the dependencies.

Information (please complete the following information):

• OS: Debian
• Browser: irrelevant
• mkdocstrings version: 0.15.0

Additional context

I've seen that the pyproject.toml file doesn't have that dependency, it asks for Jinja2 < 4.0. Maybe there was a packaging error.

Already fixed in #283, not released yet (which is why you see the error but found pyproject.toml to be correct)
