Suggested improvement on Protecting environments documentation.

The changes in this code update the documentation for protected environments in GitLab. It clarifies that when granting the "Allowed to deploy" permission to an approver group, the user configuring the protected environment must be a direct member of the approver group. It also provides more information about granting these permissions to inherited members using the API and enabling group inheritance. These updates ensure that the documentation is accurate and provides users with the necessary information to configure protected environments effectively.
