CAMEL-22545 new camel-huggingface component

[johnpoth]

Description

https://issues.apache.org/jira/browse/CAMEL-22545

This introduces a new camel-huggingface component that provides an easy-to-use integration with the Hugging Face models. It leverages the Deep Java Library (DJL) Python engine to run Hugging Face Transformers pipelines directly.

For example, to use the Qwen2.5-3B-Instruct model:

from("direct:start-chat")
    .to("huggingface:chat?modelId=Qwen/Qwen2.5-3B-Instruct");

Thanks !

Target

• I checked that the commit is targeting the correct branch (Camel 4 uses the main branch)

Tracking

• If this is a large change, bug fix, or code improvement, I checked there is a JIRA issue filed for the change (usually before you start working on it).

Apache Camel coding standards and style

• I checked that each commit in the pull request has a meaningful subject line and body.

• I have run mvn clean install -DskipTests locally from root folder and I have committed all auto-generated changes.

can this be externalised to the parent pom?

Please register the component here, so that it gets added to the catalog:

Done, thanks for reviewing!

@johnpoth this not a blocker, but what about moving the python code under the resources folder in its .py file? so that it can be retrieved and returned by these getPythonScript()

[johnpoth]

Thanks @Croway for the feedback! I've implemented the changes

We have released so the version should be bumped to 4.19.0-SNAPSHOT and so forth
