[Website]: Vulnerability Management filter on data-integrations page only shows Qualys

### Before you submit

- [x] This issue is about a documentation page, flow, or piece of content.

### Type of issue

Inaccurate

### What documentation page or section is affected

https://www.elastic.co/integrations/data-integrations?solution=all-solutions&category=vulnerability-management

### What happened?

## Summary

The Vulnerability Management category filter on the Elastic integrations page appears to be incomplete.

URL:
https://www.elastic.co/integrations/data-integrations?solution=all-solutions&category=vulnerability-management

## Actual behavior

When filtering by `Vulnerability Management`, the page only shows `Qualys`.

## Expected behavior

All integrations tagged/categorized as vulnerability management should appear when that filter is selected, not just Qualys.

Tenable Vulnerability Management
Tenable Security Center

## Additional context

If I switch to `All Solutions` (https://www.elastic.co/integrations/data-integrations?solution=all-solutions), I can see other integrations that appear to belong in the vulnerability management category, which suggests the category filter or underlying tagging may be incorrect or incomplete.
