AiOperationTypeMissingException: Method moderation does not exist on provider bedrock

Problem/Motivation

Tried to analyze text with ai_content and got:

AiOperationTypeMissingException: Method moderation does not exist on provider bedrock

I configured Moderation for Bedrock and it's model. getSupportedOperationTypes has moderation.

But it does not implement \Drupal\ai\OperationType\Moderation\ModerationInterface

Steps to reproduce

Proposed resolution

Remaining tasks

User interface changes

API changes

Data model changes
