Documentation for Knowledgebase has additional character leading to incorrect target

```
target:
type: bedrock-knowledge-base
model_id: my-model-id
knowledge_base_id: my-kb-id

```
Where type should be: `bedrock-knowledgebase`

Locate the documentation containing the shown Knowledge Base target example and compare its type value with the issue text. Change the extra hyphen so the example uses `bedrock-knowledgebase`, then verify that the documented target matches the expected configuration.
