[SPARK] JobTypeJobFacet added and used in Spark

[mattiabertorello]

Problem

Currently, a lineage backend has difficulty distinguishing between job types, Spark, DBT, and Airflow and needs regex on the _producer to get this information.
We need to add the JobType to make it more clear.

Solution

• Introduce new facet,
• Include new facet within Spark integration.

Note: All schema changes require discussion. Please link the issue for context.

• Your change modifies the core OpenLineage model
• Your change modifies one or more OpenLineage facets

If you're contributing a new integration, please specify the scope of the integration and how/where it has been tested (e.g., Apache Spark integration supports S3 and GCS filesystem operations, tested with AWS EMR).
