Array of strings incorrectly indexed as `dense_vector`

### Elasticsearch Version

8.11+

### Installed Plugins

_No response_

### Java Version

_bundled_

### OS Version

ANY

### Problem Description

When indexing an array of string values, these may be dynamically indexed as `dense_vector`. This is unexpected behavior as they should be indexed as `text`.

The error the user will see is: `:"org.elasticsearch.common.ParsingException: Failed to parse object: expecting token of type [VALUE_NUMBER] but found [VALUE_STRING]`

### Steps to Reproduce

The following yaml test reproduces the bug:
```
---
"Fields indexed as strings won't be transformed into dense_vector":
  - do:
      index:
        index: strings-are-not-floats
        refresh: true
        body:
          obviously_string: ["foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo",
                           "foo", "foo", "foo", "foo", "foo", "foo", "foo", "foo"]
  - do:
      cluster.health:
        wait_for_events: languid
  - do:
      indices.get_mapping:
        index: strings-are-not-floats

  - match: { strings-are-not-floats.mappings.properties.obviously_string.type: text }
```
