What does this PR do? A clear and concise description with your runway ticket url.

This fixes the redirection of none sense urls to the parent page if there is one otherwise, it sends the user home.

How to test? Steps to confirm the desired behavior:

Checklist:

• LABELS Add a label: enhancement, bug, improvement, new kit, deprecated, or breaking. See Changelog & Labels for details.
• DEPLOY I have added the milano label to show I'm ready for a review.
• TESTS I have added test coverage to my code.

This is how I setup the redirects:

• /kit_category/NONSENSE goes to home, or "/"
  • This does not have a parent page so I am keeping the default of redirecting home.
• /changelog/NONSENSE gives an error
  • This redirects to changelog/web since /changelog already defaults to changelog/web
• /visual_guidelines/NONSENSE goes to the colors.md but keeps the incorrect path "/visual_guidelines/NONSENSE"
  • Fixed the issue where the url does no reflect the redirect
• /guides/design_guidelines/NONSENSE gives an error (but will be updated to go to "/guides/design_guidelines" in PLAY-1426
  • Works as expected
• /samples/NONSENSE goes to "/samples"
  • Works as expected

Something I noticed and researched.

Unintended Navigation/Back Button Issues

Issue: By modifying the URL without a corresponding change in the page's content, users might expect that pressing the browser's "Back" button will navigate them to the previous page—but it might just bring them back to the same /visual_guidelines/colors path repeatedly (depending on how many times this code executes).
Fix: Use history.replaceState() instead of pushState() if you don't want to add a new history entry.

@jasperfurniss - I am thinking of making the change I brought up above. I just tested it in milano and this does add an extra history entry so I am going to try the suggestion above and see if that is a better user experience
