[Docs] Corrections needed for winlogbeat role privileges

[rseldner]

Similar to this filebeat issue: https://github.com/elastic/beats/issues/35612

The documentation for a winlogbeat_writer role appears to be missing required privileges:

• read_pipeline (cluster)
• manage(index)

The Create an API key for publishing is also missing manage index privilege

API to create a role per the documentation

PUT _security/role/winlogbeat_writer
{
    "cluster": [
      "monitor",
      "read_ilm"
    ],
    "indices": [
      {
        "names": [
          "winlogbeat-*"
        ],
        "privileges": [
          "create_doc"
        ],
        "field_security": {
          "grant": [
            "*"
          ]
        }
      }
    ]
  }

Without manage index privilege

beat log is not too explicit {"log.level":"warn","@timestamp":"2024-04-10T12:14:33.076-0700","log.logger":"elasticsearch","log.origin":{"function":"github.com/elastic/beats/v7/libbeat/outputs/elasticsearch.(*Client).bulkCollectPublishFails","file.name":"elasticsearch/client.go","file.line":454},"message":"Cannot index event (status=403): dropping event!
