Proxy: Handle non-200 HTTP codes on DASH manifests (#4429)

Browse Source 
Before this PR, Invidious assumed that fetching the DASH manifest from
YouTube will always be successful and didn't check the status code.

That meant that if YouTube gave a rate-limiting page, invidious would
return an HTTP 200 response with the 'application/dash+xml' Content-Type
header and the YouTube ratelimiting page as the body.
