Lexicon specs are missing, links 404

[str4d]

Steps to reproduce

1. Navigate to the documentation for a specific lexicon (e.g. https://atproto.com/guides/applications#appbskyfeedpost)
2. Click on its name (which in the above case navigates to https://atproto.com/lexicons/app-bsky)

Expected

I should see the app.bsky lexicon specification (ideally for app.bsky.feed.post in the above example).

Actual

A very pretty 404 error page.

[str4d]

The bad links are here:

atproto-website/content/guides/applications.md

Line 105 in d604684

### <a href="/lexicons/app-bsky">app.bsky.feed.post</a>

The lexicon specifications they linked to were removed in #283.

[str4d]

There are existing redirects for legacy lexicon subpages to the (now-removed) combined lexicon pages, that would also need to be updated:

atproto-website/next.config.js

Lines 36 to 105 in d604684

Hello, I opened PR #295 removing the links and fixing the redirects that caused the 404 error. Let's wait for the review.

I think with the above PR these are resolved. We should still update/replace these pages to not have any lexicon links, or to link to https://docs.bsky.app, but I think the urgent bug is resolved.
