nixos/nextcloud: Update logreader warning description

[provokateurin]

The error is no longer logged since nextcloud/logreader#1449. This was a bug in the app, since the error is not fixable by the admin due to the logging configuration.

Alternatively we can also keep the section, as the message is still shown, but only as info and not as an error anymore. Having the section might still be useful for some people to understand why this message appears.

I simply changed the description to match the new behavior, as the "warning" is still shown and admins might want to understand what it means.

Oof sorry this completely slipped. Taking a look...

With the last comment resolved, I think we can merge this.
Adding a backport label since the change got backported to nc 28-30 and thus it's also in 24.11, so we can also update its manual.

@provokateurin pushed 9430768. I originally wanted to remove the first sentence only, but then the rest sounded a little weird.

Let me know if you're OK with that change, then I'd merge!
That said, thanks for the upstream work for that in the logreader app :)
