Cycle dependencie when installing mkdocstrings

[Victor Mariano Leite]

Describe the bug
I have a requirements file for documentation dependencies like this:

markdown==3.*
mkdocs==1.*
mkdocs-material==7.*
pymdown-extensions==8.*
mkdocstrings[python]==0.*

But its generating an error for cyclic dependencies when we install it in a virtualenv and validate it with pipdeptree

Warning!! Cyclic dependencies found:
* mkdocstrings-python-legacy => mkdocstrings => mkdocstrings-python-legacy
* mkdocstrings => mkdocstrings-python-legacy => mkdocstrings
------------------------------------------------------------------------

To Reproduce

Create a requirements.txt file with the dependencies defined above.

Create a local virtual environment with virtualenv venv, run source venv/bin/activate (on Linux) then run pip install requirements.txt.

Install pipdevtree (pip install pipdevtree).

Run pipdeptree -l > deps.txt, see the cyclic dependencies error above.

Is this an actual error or just a warning? The message suggests it's handled by pipdeptree. Also this was already reported in mkdocstrings/mkdocstrings#376, you'll find useful information there. Closing, feel free to further comment here or in the other issue!

Forgot to close apparently.
