RequestBuilder.gzip is marked as Deprecated incorrectly

[Rocketeer007]

Describe the bug The RequestBuilder has a method gzip implemented as follows:

public RequestBuilder gzip() {
    header("Accept-Encoding", "gzip");
    return this;
}

This method is marked as @deprecated this API was implemented incorrectly

Expected behavior Looking at the code history, originally, this API also set a boolean flag on the RequestBuilder named isGzip - however, that variable was removed in c9dbe5f1f80da4a2b6f195a97d997213402c0e7c, as part of fixing #2370

Section 12.5.3 of the documentation states that adding this header is the right way to activate Gzip compression, so to me, this implementation seems correct - and it seems to work fine too.

I would suggest that either the @deprecated annotation be removed from this method, or the documentation should be updated with a correct implementation,
