feat: migrate Supported Game Files to React

[wescopeland]

I promise as more of these PRs come through they'll get smaller as the surface area of foundational work decreases 😓

This PR migrates the Supported Game Files page to React.js. There are a few changes to note:

• The page now has a meta description which provides the number of hashes available for the game.
• The copy in the embed under the page heading has been slimmed down to 3 short sentences. The first two sentences on the original page were mostly restating the same thing in different ways. I also swapped the order of the last two sentences, as we know now that people are likely to click on the 1st link they see - it would be reasonable that it's the game's forum topic.
• The mobile UX has been greatly improved. Breadcrumbs have also been removed on mobile. There is quite a bit of UX research out there which suggests breadcrumbs can cause more harm than good on mobile, especially since mobile users can backswipe. Mobile users who land on the page sideways can still click the game avatar to land on the game page.
• The page no longer requires authentication. See here.

Seeing the same console errors reported here: #2624 (comment), but otherwise seems functional.
