Use \Psr\Http\Client\ClientExceptionInterface instead of \GuzzleHttp\Exception\GuzzleException

Problem/Motivation

Since we support only Guzzle 7 in Drupal 10 we can catch \Psr\Http\Client\ClientExceptionInterface errors instead of \GuzzleHttp\Exception\GuzzleException and take a small step towards making the client used by Drupal swappable.

Follow-up from #3189301: Use \Psr\Http\Client\ClientExceptionInterface instead of \GuzzleHttp\Exception\TransferException
