Add support for YAML format of OpenAPI specification

[ChristopherL-STCU]

When I add a YAML file to the api-specs folder and then run npm run publish it results in an error.

Sample OpenAPI file:

openapi: 3.0.0
info:
  title: Simple test
  version: '1.0'
paths:
  /test:
    get:
      responses:
        '204':
          description: No response

Error:

Error: Unable to complete publishing. Error: Unable to complete OpenAPI specifications publishing. SyntaxError: Unexpected token o in JSON at position 0 at JSON.parse () at OpenApiPublisher.eval (webpack://publisher/./src/publishing/openApiPublisher.ts?:29:46) at Generator.next () at fulfilled (webpack://publisher/./src/publishing/openApiPublisher.ts?:5:58) at OpenApiPublisher.eval (webpack://publisher/./src/publishing/openApiPublisher.ts?:39:23) at Generator.next () at fulfilled (webpack://publisher/./src/publishing/openApiPublisher.ts?:5:58) at SitePublisher.eval (webpack://publisher/./node_modules/@paperbits/core/publishing/sitePublisher.ts?:40:23) at Generator.throw () at rejected (webpack://publisher/./node_modules/@paperbits/core/publishing/sitePublisher.ts?:6:65)

It seems to be trying to parse the YAML file as JSON.

Hi @ChristopherL-STCU, why would you add YAML file to specs folder? Can you please tell what are you trying to achieve?

[azaslonov]

Sorry, I didn't realize you're talking about YAML format of spec. This format is not supported yet.

Yes, that's it. Okay, thank you.
