Docs feedback: Go-get issue workaround

Not sure but I think this page would be the most appropriate: https://docs.gitlab.com/ee/development/go_guide/

There was an issue describing gitlab not support go-get with sub-groups and even though this was solved a customer had to follow a workaround to be able to use the command go-get.

The workaround was described in another customer's comment: gitlab-foss#37832 (comment 285775193)

After testing this, my customer produced a document with all the details/flow he had to follow to use this. He had to:

• Generate a new API token with api and repo read scopes.
• Create ~/.netrc with the following: machine gitlab.comlogin {username} password {api token}-
• Ensure insteadOf was removed for gitlab from ~/.gitconfig
• Run go clean --modcache
