Feature #2844 release_guide_dropdowns

[JohnHalleyGotway]

Pull Request Testing

Swinging for the fence here. I added Instructions dropdowns basically throughout the Release Guide. Replaced what I considered to be overly organized sub-sub-sub sections with bullets instead so they could fit in the dropdown. Preceeded each dropdown with a 1-sentence summary.

• Describe testing already performed for these changes:
  
  Built locally to confirm that the changes render well with no warnings.

Throughout, I didn't change the content much... basically just the formatting.
