FYI... when this PR is merged into main, we'll need to modify the commit message because it doesn't conform to the Angular style required by semantic-release :)

I found an inconsistency between the java and go examples. Can I ask you to make a small modification there too?
The include history false is missing from the following code snippet, however we have it in the java examples. It is important from that point of view we want to display the same code snippets in all the languages in the reference. It elevates user experience and makes easier to use the SDKs.
Thank you very much for your help in this case!

It(`GetAPIKey request example`, func() {
			fmt.Println("\nGetAPIKey() result:")
			// begin-get_api_key
			getAPIKeyOptions := iamIdentityService.NewGetAPIKeyOptions(apikeyID)
			apiKey, response, err := iamIdentityService.GetAPIKey(getAPIKeyOptions)
			if err != nil {
				panic(err)
			}
			apikeyEtag = response.GetHeaders().Get("Etag")
			b, _ := json.MarshalIndent(apiKey, "", "  ")
			fmt.Println(string(b))
			// end-get_api_key
			Expect(err).To(BeNil())
			Expect(response.StatusCode).To(Equal(200))
			Expect(apiKey).ToNot(BeNil())
			Expect(apikeyEtag).ToNot(BeEmpty())
		})
