Codeblock language support is insufficient

[temeddix]

The docs say that supported languages are those of Shiki.

kit-docs/packages/kit-docs/src/node/markdown-plugin/parser/plugins/shiki-plugin.ts

Line 7 in 88fa1ae

langs: ["bash", "javascript", "typescript", "svelte", "markdown", "html", "diff", "css", "json", "toml"],

However, not all languages from Shiki are included in this library.

This results in error when writing other languages, such as Python in markdown codeblocks.
