Catch internal server error from remote on decline

[VicDeo]

Description

Handle 500 exception on declining a share

Motivation and Context

Before 10.2 response for declining non-existing shares was 500
#34786 changes HTTP status from 500 to 410
But declining any non-existing share for OC lower than 10.2 still causing unhandled exception.

Any chance to refine this exception into GuzzleHttpException or something similar that might be being thrown? It's unlikely that a BlaBlaBlaException with code 500 reaches this point, but we'll have problems detecting this scenario with this code. It's the typical thing that will take a long time to detect.

changed to be \GuzzleHttp\Exception\ServerException
