Swagger Compatiblity

Hi Matthew,

I've put the swagger file into https://editor.swagger.io/ and found some errors, which were reported.
I started looking into the existing warnings and started making code changes to have them fixed.

If you like to have it, I'll provide them as PR as well (wanted to do a heads up this time).
Essentially it's:

• not having a requestBody in GET and DELETE (that's forbidden)
• not having empty format (it's default)
• removing enum = null (also forbidden)

Very nice! Please, feel free to open a PR 😄

It wouldn't surprise me if there were a few more like that, the errors I fixed during implementing were from swagger errors on the frontend.

'New-PodeOAStringProperty -pattern' does not add 'pattern' to openapi json file!

Add-PodeRoute -Path '/users/:userId'
adding a path variable produces an error (using editor.swagger.ui to verify openapi output)
Declared path parameter "userId" needs to be defined as a path parameter at either the path or operation level
