fix: respect custom query timeout in ping() method

[abodnar]

Problem

ping() creates a CurlerRequest and only calls .connectTimeOut() on it, never .timeOut(). This means CURLOPT_TIMEOUTalways falls back to the hard-coded default of10seconds inCurlerRequest, silently ignoring any value set via setTimeout()`.

Fix

Append .timeOut($this->settings()->getTimeOut()) to the request chain in ping() (src/Transport/Http.php), matching the pattern already used in newRequest():

// newRequest() — lines 274–275
$new->timeOut($this->settings()->getTimeOut());                
$new->connectTimeOut($this->_connectTimeOut);
                 
// ping() — before                                                                                       
$request->url(...)->verbose(false)->GET()->connectTimeOut(...);

// ping() — after
$request->url(...)->verbose(false)->GET()->timeOut($this->settings()->getTimeOut())->connectTimeOut(...);

Test

tests/PingTimeoutTest::testQueryTimeoutIsRespectedByPing spins up a local TCP server that completes the handshake but never sends an HTTP response. With setTimeout(1) and a high setConnectTimeOut(5), the test asserts the operation times out in ~1 second — isolating CURLOPT_TIMEOUT from the connect timeout and confirming the fix works without requiring a live ClickHouse server.
