Adding css on last line fix

[carlosmaroot]

This is the output at first with the app.add_stylesheet('css/custom.css') line error

File "/opt/Pentest-Cheatsheets/conf.py", line 187, in setup app.add_stylesheet('css/custom.css') AttributeError: 'Sphinx' object has no attribute 'add_stylesheet'

Changing the last line app.add_stylesheet('css/custom.css')

To this one app.add_css_file('css/custom.css')

The issue is from sphinx and its mentioned here https://github.com/sphinx-doc/sphinx/issues/7747
