Add archive section to each page (fixes #485)

A few notes on the implementation:

• I've not actually gone through and marked any crates as archived in this PR - I figured that could be done seperately (as a rework of Remove crates confirmed as dead #542?)
• This should work for crates, games, and resources.
• If a category has no archived crates, the section is hidden.
• As discussed on the original issue, I wasn't sure what icon to use for the section - I didn't want to go for a thumbs down or a trashcan or anything like that, as that felt too negative. I ended up going for the 'bed' icon - the implication being the crates are asleep :p

@AngelOnFira - Would you be able to give this a quick review if you get some time? I'd like to get things moving with cleaning up AreWeGameYet, but with Ozkriff taking a step back there's not really anyone else to review my PRs 😅

(I do have admin rights so I could just unilaterally merge it, dunno how I feel about that though...)

I'm going to go ahead and merge this, as I feel like there's been a consensus that the site needs something like this for a long time now, (see #95) and it'd be a shame for it to continue to be blocked into 2024.
