Function getTypesUrl

server/utils/docs/client.ts:163–177

* Get the TypeScript types URL from esm.sh's x-typescript-types header. * * esm.sh serves types URL in the `x-typescript-types` header, not at the main URL. * Example: curl -sI 'https://esm.sh/ufo@1.5.0' returns header: * x-typescript-types: https://esm.sh/ufo@1.5.0/dist/index.d.ts

(packageName: string, version: string)

 *   x-typescript-types: https://esm.sh/ufo@1.5.0/dist/index.d.ts
