fix: Update go codegen to set object as interface{}

[jeremytchang]

Currently the Go SDK Models will break on build because the type in params is set to *struct which is not valid. For now set object to interface{}. Could do map[string]interface{} in the future.

This change is needed to get integration tests to work.

Generated 4.0 Go model too.

LGTM. Does this mean the Go v3 folder is no longer being generated, too? Was that an incidental cleanup you got resolved to get the generator running correctly?

@jkaster The Go model generation issue stemmed from sdk-codegen script package.json version was incorrect. I had made Jax's change locally. https://github.com/looker-open-source/sdk-codegen/pull/976/files#diff-4b80bf2b50cec2975b7466079f3acd1355591534fd0adc381a257267a682b5d9
