feat: ✨ add `scrape_json_from_url()`

[signekb]

Description

These changes are done so we can scrape the Data Package specs for the properties template. To be able to scrape URL content, I have added requests to our dependencies (To do this, I ran poetry add requests in the Terminal).

Closes #620
