[FEAT] Consider proxy_hide_header option for Safari browsers accessing Nextcloud

[jakev383]

Is this a new feature request?

• I have searched the existing issues

Wanted change

Add the following option to the nextcloud sample configs:
proxy_hide_header Upgrade;

Reason for change

Safari browsers (both mobile and desktop) seem to encounter an issue accessing Nextcloud proxied instances. I have not seen this behavior exhibited for other proxied containers (mealie, emby, etc). The Nextcloud destination page/site fails to load and the client displays the following error:
network connection is lost
I have only seen this with Safari browsers so far - Chrome and Firefox do not seem to need this option to function as expected, nor does it seem to affect Chrome or Firefox after being implemented.
Adding the config change to the nextcloud.subdomain.config resolved the issue.

Proposed code change

Add the following to the nextcloud.sub*.config.sample files:
proxy_hide_header Upgrade;
