Dependabot: it does not work as expected

[humitos]

It seems that it upgrades the .txt file directly instead of calling pip-compile as I understood from the documentation.

See #194 where it increases the version of Sphinx when it's not possible because we are using sphinx-tabs where the latest version supported is Sphinx<5. Then, the build fails with:

The conflict is caused by:
    The user requested sphinx==5.0.1
    sphinx-autoapi 1.8.4 depends on sphinx>=3.0
    sphinx-autobuild 2021.3.14 depends on sphinx
    sphinx-prompt 1.5.0 depends on Sphinx
    sphinx-rtd-theme 1.0.0 depends on sphinx>=1.6
    sphinx-tabs 3.3.1 depends on sphinx<5 and >=2

I'm not sure how to solve this or if Dependabot is really compatible in the way I want it to work, even. The right command to execute is

pip-compile --upgrade --extra=doc --output-file=docs/requirements.txt pyproject.toml

(note that I added --upgrade, otherwise it won't look for upgraded packages)
