Description

There's existing redirect from /.well-known/carddav and /.well-known/caldav to /nextcloud/remote.php/dav/.

However, in Nextcloud version 29, it will check for /nextcloud/.well-known/carddav which Nextcloud will then resolve to /remote.php/dav/ regardless of overwritewebroot config and will not reach the Nextcloud endpoint.

Benefits of this PR and context

Removes a warning in Nextcloud's "Security & setup warnings" page

How Has This Been Tested?

Removes the warning on my configuration with default lscr.io/linuxserver/swag:2.10.0 and lscr.io/linuxserver/nextcloud:29.0.0

This is still a nice-to-have PR

As detailed in nextcloud/server#45033 (comment) and nextcloud/server#45033 (comment), Nextcloud 29 starts performing the WebDAV verifications with overwrite.cli.url which is advised to be the same as the URL in which Nextcloud is accessed through

As such, yourhost.com/subfolder/.well-known/carddav will be queried.

I have a question for contributors such as @aptalca, I am just not sure what needs to be done to get this approved
