Removed incorrect ignore_malformed query parameter.

[dblock]

Description

The documentation for put_mapping seems to imply that ignore_malformed can be specified as a query parameter. It's a valid index field mapping parameter but doesn't look like it can be specified on the query string. It's also not in the API spec.

$ curl -k -u admin:$OPENSEARCH_PASSWORD -X PUT https://localhost:9200/movies | jq
{
  "acknowledged": true,
  "shards_acknowledged": true,
  "index": "movies"
}

$ curl -k -u admin:$OPENSEARCH_PASSWORD -X PUT https://localhost:9200/movies/_mapping?ignore_unavailable=true --json "{}" | jq
{
  "acknowledged": true
}

$ curl -k -u admin:$OPENSEARCH_PASSWORD -X PUT https://localhost:9200/movies/_mapping?ignore_malformed=true --json "{}" | jq
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "request [/movies/_mapping] contains unrecognized parameter: [ignore_malformed] -> did you mean [ignore_throttled]?"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "request [/movies/_mapping] contains unrecognized parameter: [ignore_malformed] -> did you mean [ignore_throttled]?"
  },
  "status": 400
}

The ignore_throttled parameter mentioned here looks deprecated, so we don't document it, which I think is right/separate problem.
