fix: render fix in config.sample

[mmattel]

This is small render fix for config.sample.

With this, the list it will render as such (otherwise things get rendered in one line and not as list)

Post merging, I will do a config-to-docs run and add the change to the current docs-server PR of OC11

Thanks for opening this pull request! The maintainers of this repository would appreciate it if you would create a changelog item based on your changes.

The linter complaint is wrong. There has to be this kind of blank line, otherwise rendering is incorrect...

Overview

This PR adds a single blank PHPDoc comment line (*) before the "Available failover modes" bullet list in config/config.sample.php. The intent (per the description) is to fix list rendering in the generated config docs: without a blank separator line, the downstream doc generator collapses the list items onto a single line instead of rendering them as a proper bullet list.

Code quality / style

• The change is minimal, focused, and low-risk: it touches only a comment block, not executable configuration. No PHP behavior is affected.
• The added line follows the existing PHPDoc comment style of the surrounding block (* leading the line).

Specific suggestions

• Minor: the new line was committed as * with a trailing space. The repo's coding standard (and most linters) flag trailing whitespace. Prefer a bare * with no trailing space to avoid tripping whitespace checks. This is the only nit and is non-blocking.
• For consistency, it's worth confirming other similar bullet lists in this file (e.g. other "Available ..." enumerations) already have the same blank-line separator, so the rendering treatment is uniform across config.sample.php.

Potential issues / risks

• None functional. config.sample.php is documentation/template only; adding a comment line cannot change runtime config parsing.
• The real validation is the rendered output, which can only be confirmed by the post-merge config-to-docs run the author mentions. The source change itself is correct for producing a blank line in the doc source, which is the standard way to force AsciiDoc/Markdown list rendering.

LGTM aside from the trailing-whitespace nit.
