Update nginx sample configs with .well-kown webfinger and nodeinfo

[Northcode]

Noticed these redirects were missing from the nginx docs, only present in the apache ones.

RewriteRule ^\.well-known/(?!acme-challenge|pki-validation) /index.php [QSA,L]

I think we use a different rewrite rule for apache. See nextcloud/server#24860 for more details. Did you see a failing Setup Check in Nextcloud about the missing redirect?

[Northcode]

It was giving me a warning in the server settings about webfinger not being properly configured. And pointed me here:
https://docs.nextcloud.com/server/23/admin_manual/issues/general_troubleshooting.html#service-discovery
which has this rule: RewriteRule ^\.well-known/webfinger /nextcloud/index.php/.well-known/webfinger [R=301,L]

After changing the config to match what I have in this PR, the warning dissapeared.

[kesselb]

# Let Nextcloud's API for `/.well-known` URIs handle all other
        # requests by passing them to the front-end controller.
        return 301 /index.php$request_uri;

Is the rule for webfinger and nodeinfo. Is your Nextcloud installed into a subdirectory?

[Northcode]

I somehow missed that. I'm hosting via the helm chart, which uses rewrite instead of location in the nginx config.
I already made a PR for the chart, and thought it was missing from these docs too. nextcloud/helm#241

But since the rule you mentioned already achieves what I made the PR for I'm closing this then.
Thanks for the review.
