Docs Site Screenshots

Several pages updated, but here are the main two:

NOTE: You'll see that the UI screenshots in those pages aren't updated. This is expected - the docs site itself is undergoing heavy updates. That's actually why I want to get this change in now, so we don't have to redo all the screenshots again later!

Code Changes

• Update navigation, headers, buttons, drop-downs, and other references to "Subject Request", "DSR", etc.
• Update navigation, headers, buttons, drop-downs, and other references to "Datastore" or "Datastore Connection"
• Update docs for Subject Requests
• Update docs for Datastore Connections
• Update automated tests to expect new naming, IDs, etc.

Steps to Confirm

• Use nox -s test_env to test the privacy request and connection management screens
• Use `nox -s

Description Of Changes

This is a minor rename of some of the features in the UI as part of our 2.0 release, so that it's consistent with the long-term vision for these features in the roadmap ahead. The product & documentation teams have put a lot of thought into where they want to improve the navigation and terminology in the app, and I offered to do this copy editing right now so that it'd be less of a chore to redo a lot of the documentation work (especially screenshots!) in the months to come.

This is mainly just copy edits, though in some places the test code expected specific copy to run automation suites, etc. Lots of files changed, but the risk of these seems pretty minimal...

Got the 👍 from @malaethyca on the copy & nav changes, so this is ready to come in.
