Incomplete Bug: Lack of Support for Importing Swagger 3 API

Description:

I noticed that Yaak does not currently support the import of Swagger 3 APIs. This is an important feature for modern API development and integration.

Details:

• Issue: The system does not allow the import of Swagger 3 API specifications.

• Impact: Users are unable to leverage the latest API standards and cannot easily integrate their Swagger 3-compliant APIs into Yaak.

Attachments:

• swagger_3_example.json: A sample JSON document containing a Swagger 3 API specification. This file demonstrates the structure and format that Yaak should support.

Steps to Reproduce:

1. Attempt to import a Swagger 3 API specification.

2. Observe that the import functionality either fails or does not recognize the Swagger 3 format.

Expected Behavior:

• Yaak should successfully import Swagger 3 API specifications without any issues.

Actual Behavior:

• Yaak fails to import Swagger 3 API specifications, resulting in an error or failure to recognize the format.
