feat: validator for ferry trips + bikes allowance

[cka-y]

Summary:

Add a rule with a WARNING severity level that checks is bike_allowed is present for ferry trips, after the addition in MobilityData/GTFS_Schedule_Best-Practices#55.
Closes #1499

Expected behavior:

missing_bike_allowance warning notice is added to the report if ferry route types don't specify the bikes_allowed value. Valid values are 1 (bikes allowed) and 2 (bikes not allowed). Any value different from 1 or 2 will result in the warning being present in the report.

@davidgamez, does this PR have any dependencies with the automatic generation of documentation?

@cka-y I think it would be worthwhile to verify that the failing acceptance tests are consistant with the change in the code and were expected.
In such a situation I would say it's good practice to explain the test failures in a PR comment.

Since we introduced a new warning notice, some acceptance tests are failing.
After examination of the evaluation report, I can confirm that all differences are expected and related to the newly added warning notice.
