Camel 4.9 - Global data format configurations

### Describe the solution you'd like

Camel 4.9 now includes global data format configuration in the yaml DSL (similar to beans).

There is a new top level
```
- dataFormats
```

which is an array of DataFormatDefinition that are the same as in the DSL when using marshal and unmarshal.

See for example this tiny unit test
https://github.com/apache/camel/blob/main/dsl/camel-yaml-dsl/camel-yaml-dsl/src/test/groovy/org/apache/camel/dsl/yaml/DataFormatsTest.groovy

### Variant

Both

### Container Management (if applicable)

None

### Operating System (for VS Code Extension)

None

Start with the referenced dsl/camel-yaml-dsl/camel-yaml-dsl/src/test/groovy/org/apache/camel/dsl/yaml/DataFormatsTest.groovy and run the tiny unit test to understand the expected YAML shape. Trace the corresponding Camel Karavan YAML DSL handling; done means a top-level dataFormats array is supported like marshal and unmarshal for both variants.
