Description

After creating a namespace user is redirected to the URL (/ui/namespaces/<namespace>). This URL doesn't work when switching to different repositories by repo selector. We should use /ui/repo/:repo/:namespace which is already the default path for viewing namespace detail and list collections in namespace

Steps to Reproduce

1. go to namespace list in UI
2. create a namespace 
3. in namespace detail: use Filter by repository dropdown and switch to the different repository (Community, Red Hat Certified or Validated)
4. nothing happens 

Actual Behavior

• switching between repositories doesn't work with URL: /ui/namespaces/<namespace> or /ui/my-namespaces/<namespace> 
• same behavior when user edits namespace

  Expected Behavior

• switching to repo should load correct namespace content
