Sitemap ignores moderation state (Content Moderation)

Description

The module’s controller does not take moderation state into account when Content Moderation is enabled, causing nodes in non-public states (Draft, Needs Review, etc.) to appear in the sitemap.

Right now the filtering only checks the status field (published/unpublished), but in moderated workflows the actual publication state depends on moderation_state. This can lead to nodes being indexed when they shouldn’t be.

Steps to reproduce

1. Enable Content Moderation.
2. Create a workflow with non-published states (e.g., Draft).
3. Create a node of a type included in the sitemap and leave it in Draft.
4. Check the sitemap → the node appears.

Expected behavior

The sitemap should only include nodes that are actually published according to the active moderation workflow, not just by the status flag.

Technical proposal

• Detect whether the node type is moderated.
• Determine if the revision is publicly available using ModerationInformationInterface::isLiveRevision() or similar.
• Exclude nodes in non-public moderation states even if status = 1.
