Release 5.0.2 with error source fix for some downstream errors (#1980)

This PR fixes error source for 2 errors:
- parsing of invalid json response should be downstream error as we
expect to receive valid json from zabbix
- no host found error should be downstream. We are bumping sdk that
includes that fix
https://github.com/grafana/grafana-plugin-sdk-go/pull/1246.

As you can see - the invalid json parsing is now downstream error
