Catchup on redirects from transition

[kathycarothers]

What we're after:
We are looking to remove transition pages off our serves. We have around 200 links that need to be tested and then redirects put in place.

Related issues

• Transition inventory meeting (17.2)  #4995

Completion criteria

• Review Pat's testing link tab in our redirects excel sheet
• If a link is broken figure out where it should redirect
• Put in a ticket(s) to put in the redirects
• Put in a take-down ticket to take down files that can just be deleted.

Future work

• Testing tickets
• Take down tickets

This ticket was too broad. I'll continue to work through researching the list, but will split off the redirect work into its own tickets (there will be more than one), following our usual way of doing them.

First up lines 195-250 of the redirect spreadsheet in #5111
Then lines 253-259 in #5112

Take down tickets, migration tickets and redirect tickets created. Closing and we'll move on to #5112, #5122, and #5123. Most of the redirects will happen in #5111
