Description

If I have multiple $ref in my operations schema like this:

paths:
  /some-path-1:
    get:
      operationId: SomeOperationName1
      responses:
        '200':
          description: ''
          content:
            application/json:
              schema:
                $ref: >-
                  http://localhost:3000/some-other-openapi.json#/paths/~1some-other-path-1/get/responses/200/content/application~1json/schema

  /some-path-2:
    get:
      operationId: SomeOperationName2
      responses:
        '200':
          description: ''
          content:
            application/json:
              schema:
                $ref: >-
                  http://localhost:3000/some-other-openapi.json#/paths/~1some-other-path-2/get/responses/200/content/application~1json/schema

  /some-path-3:
    get:
      operationId: SomeOperationName3
      responses:
        '200':
          description: ''
          content:
            application/json:
              schema:
                $ref: >-
                  http://localhost:3000/some-other-openapi.json#/paths/~1some-other-path-3/get/responses/200/content/application~1json/schema

the generated TypeScript will be:

export type Application_1jsonSchema = components['schemas']['application~1json-schema'];
export type ContentApplication_1jsonSchema = components['schemas']['content-application~1json-schema'];
export type 200ContentApplication_1jsonSchema = components['schemas']['200-content-application~1json-schema'];

Where the 200ContentApplication_1jsonSchema is invalid name for a type in TypeScript

Reproduction

See above

Expected result

Whatever name that does not start with a number, preferably one including operationId so I from which operation it is.
