Changing from RawPath to RawQuery

[adityagarde]

There is a typo in the URLs tutorial. RawPath is used instead of RawQuery.

"Note that the Path field is stored in decoded form: /%47%6f%2f becomes /Go/. A consequence is that it is impossible to tell which slashes in the Path were slashes in the raw URL and which were %2f. This distinction is rarely important, but when it is, the code should use RawPath, an optional field which only gets set if the default encoding is different from Path."

This is coming directly from golang docs. It's not a typo. There is a significant usage for RAWPATH.
