Update docker nginx config to not force ipv6

[yxie2023]

ipv6 support is automatically added via nginx docker's 10-listen-on-ipv6-by-default.sh.

This patch allows element-web to run on system with or without ipv6 enabled.

Vote against from me :-). Sorry, my nginx does not come throough docker and I don't believe disabling IPv6 by default makes sense nowadays. Add a comment to tell people to comment this out if they don't use IPv6, but no one should be just using this config without going through it and adapting it as they need fit anyway. Don't just disable IPv6.

The config isn't intended as an example, but the config we use for our Docker image only. @yxie2023 could you move the nginx dir into a docker dir to make that clearer, then apply the same change you made therein?

done @t3chguy. let me know if there's anything else. thank you!

[t3chguy]

Looks sane to me, thanks

@yxie2023 you would need to sign the CLA if you want your contribution to be merged. Also looks like Sonarcloud won't scan your own develop branch so you'd need to contribute from a different branch name.
