Gin gorm (#6531)

* added gin-gorm tests

* added missing tests to benchmark_config.json

* added json test to benchmark_config.json

* fixed typos in readme and benchmark_json

* as pipelines are green, cleanup readme and prepare for PR

* removed binary artifact... added by mistake during first commit

* increased conn pooling and added goroutines in queries test

* do actually add goroutines

* moved the gin-gorm tests under the gin subfolder as per PR review

* patched original benckmark_config.josn file for the gin suite
