fixed basic examples for the golang SDK

[cdreier]

the examples were a bit confusing, because the hydra-client was named admin - which conflicts with the correct import for the admin.NewCreateOAuth2ClientParams call.

i had to battle a bit around, and tried to rename a few variables and added correct imports, so the examples should just work when copy & pasting

Thank you very much for your contribution to the documentation! Due to the way Docusaurus versioning works, you need to make the changes in two locations:

• docs/versioned_docs/version-v{version}/path/to/file
• docs/docs/path/to/file

Without making them in both locations, the changes will most likely be lost when releasing another version. Thank you! :)
