feat: validation rules for networks and route_networks

[cka-y]

Pull Request Description

Summary:
Closes #1618

IntroducesNetworkIdConsistencyValidator, a new validation rule in the GTFS validator suite that ensures consistency in network ID usage across the feed. This validator checks for one condition:

• Conditional Forbidden File Presence: If the network_id field is present in the routes.txt file, then neither route_networks.txt nor networks.txt files should be present.

Expected behavior:

1. @tzujenchanmbd taking a look at the spec, it looks like this is the only use case where we have conditionally forbidden files, but it's something I'll be mindful of in the future as well for other use cases.

2. Should change to duplicate_route_network_association as notice name to follow convention of our other duplicate notices: https://gtfs-validator.mobilitydata.org/rules.html (e.g duplicate_key, duplicate_column)

@cka-y Change to report table display for route_networks_specified_in_more_than_one_file:
