Enhance error messages when input is not a valid openapi

[gooplancton]

I'm trying to use openapi-tui with an openapi document generated by the elysia/swagger plugin [link].
Graphical interfaces like scalar [link] don't seem to have a problem with it.
This is a stripped down version of the document that still raises the error:

{
  "openapi": "3.0.3",
  "info": {
    "title": "Elysia Documentation",
    "description": "Development documentation",

  "paths": {
    "/users/": {
      "get": {
        "responses": {
          "200": {
            "items": {
              "type": "object",

openapi-tui -i ./api.json

openapi-tui error: Something went wrong
Error:
   0: paths: data did not match any variant of untagged enum ObjectOrRef at line 8 column 12

Hi @gooplancton 👋

I'm afraid to say that the above json file is not a valid openapi json.
Based on openapi-3.0.3 specification here description is a required field

You will be able to open the application if you add a description to response object, like this:

    "paths": {
        "/users/": {
            "get": {
                "responses": {
                    "200": {
                        "description": "get users",
                        // rest of the object
                    }
                }
           }
       }
   }

I've changed the label to enhancement in order to provider a better error messages.

Ya, I think there's a need to improve the error messages. Can't tell what's wrong with mine
