Backfill service_window_start and service_window_end data

[Alessandro100]

Describe the problem

Once the schema has been updated to include service_window_start and service_window_end they will be empty by default. We have the data to fill them in the validation report (JSON)

/v1/gtfs_feeds/{id}/datasets -> validation_report -> url_json

In url_json is a url which points to a JSON file has the properties feedInfo. feedServiceWindowStart and feedInfo. feedServiceWindowEnd

Proposed solution

[] write a script to back fill service_window_start and service_window_end in the gtfsdataset table
