People taking the self-paced course need to invite themselves as Owner

Why is this change being made?

People attending the self-paced online course https://handbook.gitlab.com/handbook/customer-success/professional-services-engineering/education-services/gitlabpmhandsonlab2 are instructed to invite themselves as Developer to the playground-repository.

However, this is technically not possible: As they are already owner of the repo they can't invite themselves with a lower role. In such case GitLab correctly shows an error.

Instead, the students should invite themselves with the Owner role. This doesn't make much sense as they are Owner already but at least they practice the step of invitation without triggering an error.
