Switch from https://iqss.github.io/dataverse-installations/data/data.json to https://hub.dataverse.org/api/installation

In #6 https://iqss.github.io/dataverse-installations/data/data.json was added but we should switch to https://hub.dataverse.org/api/installation

Heads up that we might change it to /api/installations some day:

• /api/installation should be /api/installations IQSS/dataverse-hub#21

I've switched it.

Yeah? It's compatible? That's good. You're going to commit the change to .env?
