✨ Checks mime for incorrect content type fonts

[ninadbstack]

Context:

• We know that browser does not return correct body for font responses to us and so we need to fetch it directly
• Now if server is not returning correct mimetype for font files [ if its sending application/octate-stream for example ] we didnt fetch font again as mime didnt match
• This caused errors while rendering font later in percy

Change:

• We now infer mime for all requests from url [ irrespective of original content type ] and if its font then we fetch it directly
• We dont tamper with original content type to honor browser behaviour when this gets rendered
