[BUG] errors in sample templates

[yuye-aws]

What is the bug?

I've found the sample samples in file https://github.com/opensearch-project/flow-framework/blob/main/sample-templates/alert-summary-agent-claude-tested.json is wrong.

How can one reproduce the bug?

Provision resources with this template. Then, I call predict on the created claude model. I will then meet with the following error:

{
  "error": {
    "root_cause": [
      {
        "type": "status_exception",
        "reason": "Error from remote service: {\"message\":\"prompt must start with \\\"\\n\\nHuman:\\\" turn after an optional system prompt\"}"
      }
    ],
    "type": "status_exception",
    "reason": "Error from remote service: {\"message\":\"prompt must start with \\\"\\n\\nHuman:\\\" turn after an optional system prompt\"}"
  },
  "status": 400
}

What is the expected behavior?

Both the created agent and claude model should work

What is your host/environment?

Linux. OpenSearch 2.18.

Do you have any screenshots?

Do you have any additional context?

Need to check other templates to see whether there are any errors.

May also need to check other dashboard assistant agents.

@qianheng-aws can you please investigate?

We need to add \n\nHuman: at the beginning of the prompt for model claude v1. Fixed by this PR: #958

Find out that anomaly-detector-suggestion-agent-claude.json and query-assist-data-summary-agent-claude-tested.json also has the same error. @gaobinlong and @chishui can you update the prompt as the following?

flow-framework/sample-templates/alert-summary-log-pattern-agent.json

Line 29 in b32f98b

"request_body": "{\"prompt\":\"\\n\\nHuman: ${parameters.prompt}\\n\\nAssistant:\", \"max_tokens_to_sample\":${parameters.max_tokens_to_sample}, \"temperature\":${parameters.temperature}, \"anthropic_version\":\"${parameters.anthropic_version}\" }",

Also needs these 2 PRs:

1. Remove empty model_type parameter in anomaly detector suggestion agent template #959
2. add sample templates for text to visualziation #936
