Subject: [PATCH] webview: remove KaTeX js file

Although the installation directions just say to include
katex.[min.]js unconditionally, the KaTeX JavaScript isn't actually
needed just to display existing KaTeX blocks -- only to render new
ones.

Which is good, because that's ~242K of (uncompressed) JS code that we
can do without.
