fix(openapi-3-2): add missing [ComponentsMediaTypesElement.primaryClass] query to replace-empty-element plugin

Description

In packages/apidom-ns-openapi-3-2/src/refractor/plugins/replace-empty-element.ts, the ComponentsMediaTypesElement NCE (Non-Concrete Element) — new in OAS 3.2 — is correctly imported and referenced in the ComponentsElement section (line 345). However, unlike other NCE elements, there is no corresponding [ComponentsMediaTypesElement.primaryClass] entry in the dynamic key-based NCE schema section.

Expected Behavior

A [ComponentsMediaTypesElement.primaryClass] entry should exist in the NCE section (alongside [ComponentsPathItemsElement.primaryClass], [WebhooksElement.primaryClass], etc.) to handle empty-node replacement for this element type.

Actual Behavior

ComponentsMediaTypesElement only appears at:

• Line 78: import
• Line 345: used inside ComponentsElement block

There is no [ComponentsMediaTypesElement.primaryClass] entry in the NCE section (around line 505+).

Reference

Raised in PR #5110, comment: https://github.com/swagger-api/apidom/pull/5110#discussion_r2846071887

Suggested Fix

Add the following entry to the NCE section of the schema (after [ComponentsPathItemsElement.primaryClass]):

[ComponentsMediaTypesElement.primaryClass]: {
  '[key: *]': function key(...args: any[]) {
    return new MediaTypeElement(...args);
  },
},

(The element type mapped by [key: *] should be verified against the OAS 3.2 spec for the components/mediaTypes field.)

Open packages/apidom-ns-openapi-3-2/src/refractor/plugins/replace-empty-element.ts and inspect the NCE schema section around line 505, comparing neighboring entries such as ComponentsPathItemsElement and WebhooksElement. Verify the expected element mapping for components/mediaTypes against the OAS 3.2 specification, then confirm that empty-node replacement is covered for ComponentsMediaTypesElement.
