Rename monitor-sandbox project to monitor-playground
Since we have a new group https://gitlab.com/gitlab-org/monitor/sandbox, some confusion might arise between this and the project https://gitlab.com/gitlab-org/monitor/monitor-sandbox
To avoid this, I propose renaming https://gitlab.com/gitlab-org/monitor/monitor-sandbox to https://gitlab.com/gitlab-org/monitor/monitor-playground.
A couple of notes:
- There are staging and prod variants, we should make sure we move both:
- It seems that metric embed links don't survive a project move so we should update these accordingly
- The docs about the demo environments should also be updated https://about.gitlab.com/handbook/engineering/development/ops/monitor/#demo-environments
