Call to undefined function GuzzleHttp\Psr7\build_query()

[jborland-piovan]

After upgrading the PHP SDK from 21.9 to 22.6 (which also updated guzzlehttp to 7.4.5), we are now getting an error on requests: "Call to undefined function GuzzleHttp\Psr7\build_query()".

From my research, it seems as though guzzle has deprecated and removed the build_query() function in preference to Query::build().

I also see GuzzleHttp\Psr7\try_fopen() being used which is also deprecated.
The new function is Utils::tryFopen().
