chore(config.sample.php): apply Nc coding standard

[joshtrichards]

Summary

In preparation for some other re-organizing, documentation expansion/cleanup, and config sample related changes. Seemed best to get this easy (but large in terms of line count) one out of the way first in order to streamline future PR reviews.

Only change contained in this PR is running php-cs-lint w/ our coding standard against the config sample.

Shouldn't cause any problems with the nextcloud-config-converter best as I can tell (and if it does we can remedy it easily enough).

LGTM, but please add the entire directory to https://github.com/nextcloud/server/blob/master/.php-cs-fixer.dist.php

• Needs a test run of https://github.com/nextcloud/nextcloud-config-converter to ensure that it's still extracting it properly and not making everything a code block or something.

Yeah the regex is confused in the converter. Looking at it now.

[joshtrichards]

converter fixed and tested w/ backwards compatibility in PR nextcloud/nextcloud-config-converter#11

(will need a docker image update pushed to production before it'll be live)

[ChristophWurst]

Backports might be painful for a while but 👍 since we are past feature freeze

[joshtrichards]

The Docker image used to do the conversion still needs a bump:

https://github.com/nextcloud/docker-ci/pkgs/container/continuous-integration-translations-documentation-sync

The old version of the sync script is still running and it's currently breaking config documentation.

I lack privileges to bump the image in docker-ci so can someone with privs do so?

Should be fixed now

Confirmed. Working now. Thanks!
