[PATCH v2] docs: set the GID in the .env file

[Daniel Axtens]

I was sure I had sent a patch for this thing before, and sure enough, I
had: commit f6f297e74a5a ("README: fix .env")

As it turns out I had only fixed README.md, not the docs. My method in
README.md is different, but also a bit more obtuse. So while in theory I
think it's good to have the method the same, in practise I'm not going
to try to standarise it right now!

All of which is a long way to say, I have applied your patch.

Pranav, welcome to the Patchwork project! We're not super quick at
responding (Stephen and I), so thanks for your patience. I can't speak
for Stephen, but for me, my day-job is only tangentially patchwork
related, so I tend to do things in unpredictable bursts. I hope that
with Lukas' wise guidance that won't be too much of a problem for you!

Regards,
Daniel
