[BUG] invalid `dynamic_template` (includes auto-generated `"type": "object"`)

[rursprung]

see opensearch-project/spring-data-opensearch#437
this seems to come from this client

What is the bug?

using dynamic_template generates a wrong template (it includes "type": "object") which then leads to wrong behaviour when ingesting field names with dots in it.

the problem seems to come from here:

opensearch-java/java-client/src/generated/java/org/opensearch/client/opensearch/_types/mapping/Property.java

Line 1440 in 61567fa

op.setTypeProperty("type", Kind.Object.jsonValue());

which was previously here (got moved around in a recent re-generation):

opensearch-java/java-client/src/main/java/org/opensearch/client/opensearch/_types/mapping/Property.java

Line 1494 in 3955240

op.setTypeProperty("type", "object");

How can one reproduce the bug?

see opensearch-project/spring-data-opensearch#437

What is the expected behavior?

the provided example works both with the old and new client. more concretely: opensearch-java mustn't inject "type": "object" into the dynamic_template

@rursprung It'd be really helpful if you could replicate/isolate the bug using just opensearch-java
