Expected Behavior

Usage of @Deprecated() on @FormField() should set deprecated: true correctly, like in the doc here.

Example:

@Get("v2")
public async findV2(
  @FormField() text: string,
  @Deprecated() @FormField() dontUse?: string
): Promise<any> {

}

Current Behavior

No deprecation is generated in openapi.json.

Context (Environment)

Version of the library: 4.1.3 Version of NodeJS: v16.17.1

• Confirm you were using yarn not npm: [ ]

I’ll check but it should work just fine. If you check the CI we are running the tests in node 16.
