feat(web): include custom nginx conf files

[emrahcom]

PR adds an include line into Nginx config to allow custom configuration in it.

Like include /etc/jitsi/meet/jaas/*.conf line in jitsi-meet.example.

In my use-case, I will add my OIDC backend as proxy by creating a config file in this folder.
Not having this folder (/config/nginx-custom/) by default is not a problem for Nginx.

If I modify that line myself at meet.conf, nothing happens when I run: docker compose up -d.

Why when you change something at rootfs it won't work in the docker container?

Need some help here, thank you so much for you contribution. I hope your feature will be integrated soon.

Hi @atlashour, this change has no effect if you don't have custom config files in /config/nginx-custom but if you want to inject some additional configs into Nginx then you may put them into this folder as files.

This type of customization is needed in some setups.
