Remove "sphinx_rtd_theme-hotfix.css"

[rmk135]

File sphinx_rtd_theme-hotfix.css that was added in https://github.com/ets-labs/python-dependency-injector/releases/tag/3.11.3 needs to be removed when https://github.com/rtfd/sphinx_rtd_theme release version 0.2.5 on PyPi and then it goes to be default version on ReadTheDocs.

Also docs/conf.py should be cleaned up from next lines:

def setup(app):
    app.add_stylesheet('sphinx_rtd_theme-hotfix.css')
