DB update workflow change PROD DB schema from main branch

[davidgamez]

Description

Currently, the DB update workflow get dispatched by add feeds operations on the catalog repository. This action updates the DB schema to the latest main schema. The side effect is that we release DB changes without its Python-supported code. Luckily, there hasn't been any issue until now, as we have been making backward-compatible changes. However, this is a high-risk situation that can lead to PROD issues.

Proposed solution

Migrate the DB update workflow to a cloud function. The cloud function can be triggered by an event or direct call from a workflow.

• Create cloud functions with the populate script GBFS and GTFS
• Unit tests for cloud function
• Update or create terraform script for deployment
• Update the Github action to call the function
