unable to add or delete environment variables to project or environment

[twardnw]

Describe the bug
Post RBAC integration, a user is unable to add any environment variables to a project or environment, the operation performs as expected for a user with an existing admin token.

To Reproduce
Steps to reproduce the behavior:

1. As a user who is of OWNER|MAINTAINER|DEVELOPER attempt to add an environment variable to a project or environment

mutation mutation1 {
  addEnvVariable(input:{
    type:PROJECT
    typeId:11
    scope:GLOBAL
    name:"TESTING"
    value:"CHECK"
  }) {
    id
  }
}

For all cases, attempting to add a PROJECT environment variable results in

Unauthorized: You don't have permission to \"project:add\" on \"env_var\".

Attempting to add an ENVIRONMENT environment variable results in

Unauthorized: You don't have permission to \"environment:add:undefined\" on \"env_var\".

For the deleteEnvVariable mutation the results are similar.

Expected behavior
Environment variable should be saved\deleted to\from the API

Appears that the issue is still there for OWNER adding a project level env var

"message": "Unauthorized: You don't have permission to \"project:add\" on \"env_var\".",
