Description of the problem, including code/CLI snippet

Since Pipeline inputs are official now the python-gitlab should support it in trigger_pipeline, too.
It seems it was not added:
https://github.com/python-gitlab/python-gitlab/blob/main/gitlab/v4/objects/projects.py#L427

    def trigger_pipeline(
        self,
        ref: str,
        token: str,
        variables: dict[str, Any] | None = None,
        **kwargs: Any,
    ) -> ProjectPipeline:

Expected Behavior

Add parameter for Pipeline inputs.

Actual Behavior

Not possible with trigger_pipeline
