This is a task to set up a Project (e.g., "Wikimedia") in growthbook-next.wikimedia.org and growthbook.wikimedia.org, align experiments (and their related data / configuration as appropriate) with the Project, and update existing Read Only or CustomElevatedAccess users to only have their role assignment within that Project, confirming that access to read query results or create experiments no longer works if the GrowthBook role access isn't pinned to the Project, but does work if access is pinned to a Project.
By the way, I ( @dr0ptp4kt ) see a small number of Read Only users whose access by way of the Project does not seem necessary at this point; if they're not in T419021: LDAP ("Bitu") group membership assignments for tiered access to GrowthBook they shouldn't get role membership in the Project, I think.
This is being dropped into Sprint 21, but could be dragged to a following sprint.
DP SRE added as subscribers for visibility. It is necessary for the automation script work to be able to synchronize LDAP/Bitu group membership to a GrowthBook role confined to a Project.
