Colons declared in model property names removed

[smasala]

Description

As discussed with @wing328:

swagger-api/swagger-codegen#4290 (comment). We have some models where the JSONProperty is set to a colon notated name. Due to the fact that the colons are automatically removed from the property name, the interfaces generated (typescript) are no longer identical with the JSON produced. We then need to resort to ts hacks such as:

myVariable['my:prop:name' as keyof MyModel] as string

@wing328 We've now migrated over to OpenAPI Generator from Swagger Code Gen. The colons are now present in the typescript interface property names but without quotation marks.

interface MyTSInterface {
   my:prop: 'hello';
}
