Change dataformats for non-deprecated comparisons

[vevetron]

…parisons

Description

Changes some data formats so we don't get errors anymore. Comparing datetimes to timestamps still seems super messy though, not sure what a better way should be.

Resolves #325

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation

How has this been tested?

poetry run make data
Ran locally to produce data, works now. Visually checked data types and compared to known working data, looks okay. But have not looked at it in a website.
edit - Built website locally and compared it to current production site and it looks good.

2_ave_median_tu_age.json
[
    {
        "organization_name": "Alameda-Contra Costa Transit District",
        "calitp_itp_id": 4,
        "service_date": 1717200000000,
        "avg_median_trip_update_message_age": 159.6283524904
    },

2_ave_median_vp_age.json
    {
        "organization_name": "Alameda-Contra Costa Transit District",
        "calitp_itp_id": 4,
        "service_date": 1717200000000,
        "avg_median_vehicle_message_age": 16.0
    },
