treewide: update to VuePress 2.0.0-rc0, switch to emiyl's theme rewrite

[lifehackerhansol]

• We can finally use Node 20
• Translations will be temporarily borked until Crowdin does its replication
• Move some configs around to align with new theme
• Searchbar is gone

Drafting until the issue with ads is fixed

[emiyl]

why was

        docsBranch: "master",
        docsDir: "docs",

removed?

all looks good to me aside from that

You don't have it in cemu guide either.

[lifehackerhansol]

I readded it anyway since it's useful otherwise.

i'm also pretty sure that

[ 'script', {}, 'if (localStorage.getItem("vuepress-color-scheme") === "dark" || (localStorage.getItem("vuepress-color-scheme") !== "light" && (window.matchMedia && window.matchMedia("(prefers-color-scheme: dark)").matches))) document.documentElement.classList.add("dark");' ]

isn't needed anymore. unsure why it was there to begin with, probably some issue with a beta version

[emiyl]

also docs/.vuepress/components and docs/.vuepress/styles can be removed

Ad issue fixed

need to fix sidebar, that died

[emiyl]

sidebar has issues in dev mode, seems to work fine on prod
