Webhooks with multiple OpenAPI files always load first file alphabetically

[s2software]

When using separate language-specific OpenAPI files for webhooks, Mintlify ignores the specified file path and always loads the first file alphabetically.

For example:
webhook-en.mdx:

---
title: 'New Plant'
openapi: '/api-reference/openapi-en.json WEBHOOK /plant/webhook'
---

webhook-it.mdx:

---
title: 'Nuova pianta'
openapi: '/api-reference/openapi-it.json WEBHOOK /plant/webhook'
---

• webhook-it.mdx displays openapi-en.json content
• Appears to select the first OpenAPI file alphabetically

However, testing with other REST methods (GET, POST, DELETE) works correctly.
So the issue is just with WEBHOOK.
