GCP-8706: fix for the ff:

    * DONE - We should add an "Open" button next to the Basic Details heading to give the user a very easy and obvious way to begin working with the nursery.
    * DONE - Close All Tabs should be on the same line as Review Nursery Details.
    * DONE - Why is the description of the variable in the tables not aligned under the Description heading? This is inconsistent with the view on the Nursery Setting tab. (Create Nursery Screen)
    * DONE - Pop-up that shows variable details:
  Title should be Details for [Variable Name]
  Labels should be bold.
    This applies also on the Nursery Settings tab
