### Problem Description

Searching a filtered and a non-filtered data stream alias that both point to the same datastream currently filter the result set 
(relevant [code](https://github.com/elastic/elasticsearch/blob/main/server/src/main/java/org/elasticsearch/cluster/metadata/IndexNameExpressionResolver.java#L714)  )

The desired behaviour is to **not** consider the filter in this case and return the (wider) un-filtered result.

(the desired behaviour for data stream aliases currently exists for indices aliases - relevant code that abandons applying the filter for _index aliases_ is [here](https://github.com/elastic/elasticsearch/blob/main/server/src/main/java/org/elasticsearch/cluster/metadata/IndexNameExpressionResolver.java#L743) )

### Steps to Reproduce

```
PUT _index_template/datastream-template
{
  "index_patterns": [
    "my-datastream"
  ],
  "data_stream": {
  }, 
  "template": {
    "aliases": {
      "first_alias": {
        "filter": {
          "term": {
            "message": "first"
          }
        }
      },
      "second_alias": {}
    }
  },
  "composed_of": []
}



POST my-datastream/_doc
{
  "message":"first",
  "@timestamp":"2023-05-02T08:02:40.420Z"
}


POST my-datastream/_doc
{
  "message":"second",
  "@timestamp":"2023-05-02T08:02:40.420Z"
}

GET first_alias,second_alias/_search
```

The `GET first_alias,second_alias/_search` call only returns one hit, while it should return 2.
