[🐛 Bug]: When encounter an exception in RemoteWebDriverBuilder.build(), the underlaying HttpClient resources are not released

[jacklee1983]

Description

var webDriver = RemoteWebDriver.builder().address(REMOTE_URL).build()
In the above code when there is an exception in the build() method, no webDriver instance returned and I cannot release the underlaying HttpClient resources. Could we consider releasing the HttpClient resources inside the build() before throwing an exception?
The exception example :

org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: java.io.IOException: Proxy-Authenticate header missing for response code 407
at org.openqa.selenium.remote.ProtocolHandshake.createSession(ProtocolHandshake.java:114)
at org.openqa.selenium.remote.ProtocolHandshake.createSession(ProtocolHandshake.java:75)
at org.openqa.selenium.remote.RemoteWebDriverBuilder.getRemoteDriver(RemoteWebDriverBuilder.java:394)
at org.openqa.selenium.remote.RemoteWebDriverBuilder.build(RemoteWebDriverBuilder.java:366)

Reproducible Code

var webDriver = RemoteWebDriver.builder().address(REMOTE_URL).build()

Debugging Logs

In the newest 4.32 version. the RemoteWebDriverBuilder.getRemoteDriver() method still doesn't release the HttpClient resources before throwing an exception.
