[FEATURE] Remove reconcilation of initialOrgManagers in CloudfoundryEnvironement

[sdischer-sap]

Is your feature request related to a problem? Please describe.
Other then the name suggest the initialOrgManagers field in the cf environment CR, is being reconciled.

It acts as a single source of truth, meaning it removes all users that are not listed there from being a manager and thus conflicts with usages of the OrgMember kind.

Also the guide reflects a different behaviour.

Describe the solution you'd like
The reconcilation logic of that field should be removed. The users should be assigned the role only on initial creation, there should be no drift detection after that. Ideally this is also prevented on schema level. It should be also part of the in-code documentation, so that it shows up in the CRD Browser as well.
