[Issue 92] Fixing Powdr Scrapers

[Rogibb111]

It looks like the Powdr resorts api has changed its domain from www.<resort>.com/api to api.\.com/api. Funny enough, the change went through for both copper and eldora, but they only removed the old API domain for eldora, but kept it for copper (so the copper scraper was still working). This PR updates both scrape URLs to use the new domain. The JSON payload for both resorts had changed a little bit, so it wasn't grabbing the data anyways. This PR changes include:

• Updating Powdr resort scrapers with the correct URLs
• Changing scraper logic to look at right JSON key for data

Closes #92
