[Bug]: Find a better way to get program courses for more reliable data

### What happened?

Currently in our sync job, we fetch program courses from Cheminot but it will soon be deprecated.

I've created a GUS ticket for that but it will take some time to be processed..
[[Link ticket #550268](https://gus.etsmtl.ca/c2atom/portal#/ticket-form/550268)] :
- 1. création de endpoints pour les détails d'un cours (id, title, code, description)
- 2. Un endpoint pour avoir la liste des cours par programme.

### What is the expected behavior?

move out from Cheminot and use ÉTS official API

### Steps to reproduce

One course that i could think of that is not a correct data is GPE450 that should be in program genie logiciel (in prod environnement)

### Screenshots and additional context
