It seems mapping update for "date_range" field type is not idempotent

Hi. Want to confirm the issue before posting it on github. ES does not allow to update date_range field with exact same mapping settings and responds with 500. Tried with docker container (Docker Hub) 7.10.1 and 7.10.2.
Here are the steps to reproduce:

### add new index
$ curl -XPUT http://localhost:29200/test_index
{"acknowledged":true,"shards_acknowledged":true,"index":"test_index"}

### check settings
$ curl -XGET http://localhost:29200/test_index
{
  "test_index": {
    "aliases": {},
    "mappings": {},
    "settings": {
      "index": {
        "creation_date": "1612290812518",
        "number_of_shards": "1",
        "number_of_replicas": "1",
        "uuid": "jQ2IEe5VTkKgWVnBfDxvoA",
        "version": {
          "created": "7100299"
        },
        "provided_name": "test_index"
      }
    }
  }
}

### add date_range field
$ curl -XPUT http://localhost:29200/test_index/_mapping -H 'Content-Type: application/json' -d '{"properties": {"range": {"type": "date_range", "format": "yyyy-MM-dd"}}}'
{"acknowledged":true}

### ensure mapping is updated
$ curl -XGET http://localhost:29200/test_index/_mapping
{
  "test_index": {
    "mappings": {
      "properties": {
        "range": {
          "type": "date_range",
          "format": "yyyy-MM-dd"
        }
      }
    }
  }
}

### try to put exact same settings for "range" field
$ curl -XPUT http://localhost:29200/test_index/_mapping -H 'Content-Type: application/json' -d '{"properties": {"range": {"type": "date_range", "format": "yyyy-MM-dd"}}}'
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_state_exception",
        "reason": "[index.version.created] is not present in the index settings for index with UUID [null]"
      }
    ],
    "type": "illegal_state_exception",
    "reason": "[index.version.created] is not present in the index settings for index with UUID [null]"
  },
  "status": 500
}

Expect to see just confirmation, but get that odd error. Btv, this does not happen with integer or keyword fields.
