Fontawesome console tab icons not appearing in locally generated html docs

[James Beard]

When generating HTML django docs locally the console tab icons (Windows, Linux, Mac) are broken and appear as missing unicode squares.

To reproduce, check out the django source, install docs dependencies, and run make html in docs/. On relevant pages e.g. ​http://localhost:3000/topics/install the icons in the tabs above the console blocks look like this: □/□ □

The cause is in the default djangodocs theme and is twofold:

1. the static file console-tabs.css contains a dynamic path meant to be interpreted, however that file is just copied verbatim by sphinx
2. the @font-face name defined in fa-brands.min.css doesn't match what's used elsewhere in the theme CSS

Have a fix already so happy to take ownership if accepted.
