Move Cluster menu entry up in the list

Description

When using the navigation left sidebar, we have the CI/CD > Cluster entry that is the last in the list. I think we should move it up to make it more consistent with the flow.

At the moment we have:

  1. Pipelines
  2. Jobs
  3. Schedules
  4. Environments
  5. Charts
  6. Cluster

Proposal

Move CI/CD > Cluster entry before Charts, since it is related to Environments. In this manner, we can also increase visibility of the feature.
