[BUG] FAQ states python 2 is used

[mutax]

The FAQ in /docs/faq.rst states that graphite is written in Python 2 which might scare people away in 2022.
The information seems just outdated and setup.py reflects that current python versions are indeed supported.

Yes, thanks for noting, @mutax !
Python 3 is indeed supported and we want to deprecate 2.7 officially soon too.

The FAQ at https://github.com/graphite-project/graphite-web/blob/master/docs/faq.rst still claims that graphite-web is written in Python 2....

[deniszh]

I will amend FAQ when we decide to abandon 2.7 (which probably will happen soon, because no current Django has 2.7 support anyway).
