OpenAPI schema code block not colored

[LeRoiLambda]

When viewing documentation pages that use the openapi-schema directive to embed schema code blocks, the syntax highlighting for the code-group is no longer applied.

Steps to Reproduce

1. Create an OpenAPI file (e.g., openapi.yaml) in your project with the following contents:

   openapi: 3.0.0
   info:
     title: Simple Order API
     version: 1.0.0
   servers:
     - url: https://api.example.com/v1
   paths:
     /order-items:
       get:
         summary: Retrieve a list of order items
         responses:
           '200':
             description: A JSON array of order items
             content:
               application/json:
                 schema:
                   type: array
                   items:
                     $ref: '#/components/schemas/OrderItem'
   components:
     schemas:
       OrderItem:
         type: object
         description: An item in an order
         properties:
           id:
             type: integer
             format: int64
             description: Unique identifier for the order item
           name:
             type: string
             description: Name of the product
           quantity:
             type: integer
             description: Number of items ordered
           price:
             type: number
             format: float
             description: Price per item
         required:
           - id
           - name
           - quantity
           - price
   

2. Add an MDX page (e.g., order-item.mdx) that references the schema:

   ---
   openapi-schema: OrderItem
   ---
   

3. Build your Mintlify documentation site.

Expected Behavior

The code block generated by openapi-schema should have syntax highlighting applied.

Actual Behavior

The schema block renders without syntax highlighting:
