Role names templated in base chart, and hardcoded in main chart

[askarbozcan]

In theia cloud (main) chart, names referenced service-role.yaml and operator-role.yaml are not templated and assume the default values from values.yaml in Theia cloud base.
Namely, operator-api-access and service-api-access.
Those are the default role names in base, however in base they can be templated.
In the main Theia cloud chart, the default role names are hardcoded.
