Table-of-contents sidebar link uses full sentence instead of short label (e.g. SeverityMatchFilter page)

On https://checkstyle.org/filters/severitymatchfilter.html, the "On This Page" sidebar TOC shows:

Examples • For example, the following configuration fragment directs the Checker to not report audit events with severity level info

Every other TOC entry on the page is a short label (Description, Properties, Example of Usage, Fully Qualified Name...), but this sub-item is the entire first sentence of the Examples section's intro paragraph, rendered as a single nav link. This makes the sidebar hard to scan and looks unintentional next to the short entries around it.

This was previously touched in #21570 (a TOC label was called out and reportedly "updated"), but the live site still shows the full sentence — worth checking whether that fix regressed, only changed a different label, or never actually shortened this specific sublink text.

Suggest replacing the sublink text with a short label like "Example 1" or "Configuration Example," and checking whether the same auto-generated-from-paragraph pattern affects other filter/check pages with example sub-anchors.
