kedro-airflow: Incorrect node names in created DAGs

[ankatiyar]

Description

This bug is not in the released version of kedro-airflow 0.8.0 but possibly introduced in one of the recent PRs after the release.

The node names in tasks in the DAGs generated by kedro-airflow have hyphens instead of underscores which are mean that the node names are not valid.

Context

What is generated now -

  "preprocess-companies-node": KedroOperator(
            task_id="preprocess-companies-node",
            package_name=package_name,
            pipeline_name=pipeline_name,
            node_name="preprocess-companies-node",
            project_path=project_path,
            env=env,
        ),

What should be generated (and previously was) -

"preprocess-companies-node": KedroOperator(
            task_id="preprocess-companies-node",
            package_name=package_name,
            pipeline_name=pipeline_name,
            node_name="preprocess_companies_node",
            project_path=project_path,
            env=env,
        ),

Steps to Reproduce
