Incorrect nginx config example

[VorpalBlade]

I tried just doing a PR for this (see #47), but I'm not signing a CLA. So you get to fix this yourself instead.

See the description of the PR for what is wrong. (Yes I'm rather annoyed right now: I consider CLAs an anti-pattern, and is what lead to relicensing and failure like Terraform, MongoDB etc. I'm frankly disappointed that you are doing that BS.)

Also, JMAP doesn't work properly since websockets aren't proxied by default. See https://nginx.org/en/docs/http/websocket.html

Oh and your example doesn't enable listening on IPv6 either.

Just to clarify, it's not a standard CLA, Stalwart uses a Fiduciary License Agreement from the Free Software Foundation Europe. Your contribution has to always remain open source otherwise the rights you are granting us are reverted back to you.

@mdecimus I'll admit: the terminology of CLA made me see red. Perhaps change the wording the bot uses to avoid those poisoned terms.

However, I don't have the time nor energy to read through and check the FLA currently though, so I would advice you to just fix the nginx documentation yourself instead.
