file.

YES

## What kind of change does this PR introduce?

Bug fix

## What is the current behavior?
The apps/learn and apps/ui-library applications fail to start in
development mode (pnpm dev) and during production builds. This is caused
by a conflict between Next.js 16, which enables Turbopack by default,
and the Contentlayer plugin, which injects a custom Webpack
configuration.

Error: ⨯ ERROR: This build is using Turbopack, with a webpack config and
no turbopack config.

## What is the new behavior?
This PR adds the required turbopack configuration block to the
next.config.mjs files for both apps/learn and apps/ui-library.

It explicitly enables Turbopack while providing the raw-loader rules for
*.md files. This ensures that Contentlayer can correctly process
Markdown content under Turbopack.

Reference: This fix follows the established pattern used in the Design
System
[#39890](https://github.com/supabase/supabase/pull/39890/changes#diff-07283a8ef455ee1c6769cb991039300209d540dd727e3434b070d03075ced551)
and Studio to handle the Contentlayer/Turbopack conflict.

## Additional context
Verified that `pnpm dev` starts successfully for both apps after the
change.
Verified that `pnpm build` completes successfully using the Turbopack
engine.
