request-response: Inconsistent documentation.

[vnermolaev]

Summary

As part of PR #4371, methods request_response::Behaviour::add_address and request_response::Behaviour::remove_address have been deprecated however in the master branch it says that

    /// Initiates sending a request.
    /// ...
    /// > **Note**: In order for such a dialing attempt to succeed,
    /// > the `RequestResonse` protocol must either be embedded
    /// > in another `NetworkBehaviour` that provides peer and
    /// > address discovery, or known addresses of peers must be
    /// > managed via [`Behaviour::add_address`] and
    /// > [`Behaviour::remove_address`].
    pub fn send_request(&mut self, peer: &PeerId, request: TCodec::Request) -> OutboundRequestId { ...

IMO, this note is obsolete and should be removed.

Expected behavior

Documentation should not mislead.

Actual behavior

Documentation misleads into using deprecated methods.
