Strip date of milliseconds to fix 4:07 error

[alanna-zhou]

Overview

The date time we get from TCAT has changed format sometime over the summer. They now include milliseconds unfortunately. We need to revert this format back to what it was so that clients don't break.

Date format we had before that we should maintain: yyyy-MM-dd'T'HH:mm:ssZZZZ
Date format that TCAT changed to over the summer: yyyy-MM-dd'T'HH:mm:ss.SSSZ

Changes Made

• Stripped milliseconds off dates from TCAT if they exist
• Updated docker-compose.yml so we can run things locally with this change
• Updated the ghopper Dockerfile because Tom sent me data manually (can't fetch from the URL) so to keep versions matching with docker images, we should have master keep this change--once we can start fetching again (Aug 30), I'll update master

Test Coverage

• Currently deployed on prod and dev from my branch and all is well
  • A temp fix similar to this one is currently deployed on prod from my branch as transit-node:v1.1.4
  • This PR fix is currently deployed on dev as transit-dev:date
• We need to add a test on integration that ensures that our date formats are correct! Made an issue on the integration repo here.
