How to add Shiki langs?

[tisonkun]

I define my own language highlight solution, and now build failed with:

 ⨯ ./content/reference/commands/query-operators/set.md?collection=reference&hash=1751537642116
ShikiError: set.md:ShikiError: Language `scopeql` is not included in this bundle. You may want to load it from external source.
    at Array.map (<anonymous>)
Import trace for requested module:
./content/reference/commands/query-operators/set.md?collection=reference&hash=1751537642116
./src/.source/index.ts
./src/lib/source.ts
./src/app/reference/[[...slug]]/page.tsx

Since rehypeCode is applied by default, I don't know how I can pass shiki config to it to extend langs.
