Cannot use spark_event_logs_s3_uri in PySparkProcessor job

[swademb]

PySDK Version

• PySDK V2 (2.x)
• PySDK V3 (3.x)

Describe the bug

Similar to #6252 - PySparkProcessor run no longer handles spark_event_logs_s3_uri due to changes in the ProcessingOutput interface - e.g. regression introduced in 3203e49

To reproduce

Provide any (valid) S3 URI for the spark log location.

Expected behavior

Successfully starts the job.
