URL redirect categories + articles: file picker to easily redirect to KO files

We received a lot of great feedback in our first annual customer survey. While we're still specing out and scoping a lot of the feedback, we have released our first small feature enhancement that was a customer suggestion in the survey.

When you're configuring a URL redirect category or setting up an article to have a URL redirect:

We've added an Redirect to File button into the editor to make it easy to browse to a file stored in KnowledgeOwl and add the URL, without having to copy and paste the URL in from somewhere else. You can also upload a new file directly to KO from within this pop-up!

We hope this makes it faster and easier to set up redirects directly to files stored in KnowledgeOwl.
