[BUG] custom analyzers not supported

[rursprung]

What is the bug?

while there's the generated Analyzer class it does not list all analyzers (e.g. phone and phone-search, introduced with 2.18, are not yet present there) and i'm also not sure how that should be used with spring-data-opensearch' @Field annotation (which takes a string, not an enum).
when using a string in the annotation, e.g. @Field(type = FieldType.Text, analyzer = "phone", searchAnalyzer = "phone-search") this works fine with ORHLC, but it fails when switching to opensearch-java:

the error message is completely unclear and it's not obvious that this is due to the analyzer.

How can one reproduce the bug?

try to use the phone analyzer on a field using spring-data-opensearch with opensearch-java.

What is the expected behavior?

it is possible to use all analyzers, regardless of whether they are built-in or custom (e.g. by defining one in settings.analysis.analyzer and using that e.g. using @Setting in spring-data-opensearch).

What is your host/environment?

• spring-data-opensearch:1.6.2
• opensearch-java:2.22.0

Do you have any screenshots?

n/a

Do you have any additional context?

#779 is related to this.

interestingly enough i also get the same error in a second case:
namely i get it when i don't reference the analyzer from an @Field yet but have a @Setting importing a custom settings JSON which contains a custom analyzer, e.g.:

{
  "analysis": {
    "analyzer": {
      "phone-ch": {
        "type": "phone",
        "phone-region": "CH"
      },
      "phone-search-ch": {
        "type": "phone-search",
        "phone-region": "CH"
      }
    }
  }
}
