Redirect to new info site

[TaiWilkin]

Overview

Some pages on the map site have been moved to the info site.
When users attempt to access the obsolete links, they are redirected
to the appropriate page on the info site.

Connects #1508

Notes

React-Router 'Redirects' don't work as expected for external routes (they add the new route as a path at the end of the url instead of rerouting), so a manual redirect was required.

Testing Instructions

• Run ./scripts/server
• Attempt to access http://localhost:6543/about/processing. It should redirect to https://info.openapparel.org/how-the-oar-improves-data-quality and clicking the back button shouldn't return you to /about/processing.
• http://localhost:6543/about/claimedfacilities should redirect to https://info.openapparel.org/resources-stories/claim-a-facility
• http://localhost:6543/tos should redirect to https://info.openapparel.org/terms-of-use
