Docs export is broken

[cwegrzyn]

Seems like a change in... something (Obsidian? Webpage export plugin?) has broken the documentation export. Nearest I can tell, the problem is that the Iron Vault styles become unnested when exported. Possibly related to KosmosisDire/obsidian-webpage-export#565

I was able to replace the other-plugins.css that the exporter generates with ironvault's direct styles.css, and it seems to fix things. We'll have to do this on every export until this is resolved.
