Incorrect help text for deploy token permissions

Summary

The help text for the deploy token scope write_registry was incorrect. It stated that the scope allowed the deploy token to create, update, and delete container images, but it actually only allows the deploy token to create and update container images as stated in the documentation, see https://docs.gitlab.com/user/project/deploy_tokens/#scope .

Deploy token documentation	Deploy token scope help text
https://docs.gitlab.com/user/project/deploy_tokens/#scope	"Project settings" => "Repository" => "Deploy tokens"

In order to avoid confusion, we should change this.

Steps to reproduce

1. Go to "Project settings" => "Repository" => "Deploy tokens"
2. Create a new deploy token and check the help text
