Context

This validator contains a section that lists the GTFS Components present in the data (see below for Pathways). This has been introduced in #1389.
Currently, we track:

• Fares v1: if fare_attributes.txt is present and has at least one record.
• Fares v2: if fare_products.txt and fare_leg_rules.txt are present and each has at least one record
• Pathways: if pathways.txt is present and has at least one record

Issue

Add a "Transfers" component to this list. We consider this component present if transfers.txt is present in the data and has at least one record.
