OpenAPI Spec: Isomnia makes servers required and non-empty while that's not a requirement in OpenAPI

### Expected Behavior

Operation description seems to be another value that Insomnia makes mandatory but it doesn't seem mandatory in the OpenAPI spec.

I'm wondering why the discrepancies?

Insomnia makes servers and operation-description mandatory.

The issue names no files, tests, or entry points. Start by locating Insomnia's OpenAPI import or validation handling, compare its treatment of servers and operation descriptions with the OpenAPI specification, and verify that valid documents without those required values are accepted.
