Describe the solution you'd like

• The idea is to provide additional config to overwrite or add JSON spec attribute after fetching from URL, URLs or local path

Describe alternatives you've considered

• This is my draft PR: https://github.com/swagger-api/swagger-ui/pull/9614
• Sorry, Frontend is not my expertise, but hopefully you could understand the idea

Additional context

• Sometimes the service returns JSON spec is underlying gateway domain. Service doesn't need to know about it's domain. And the server domain could be controlled by DevOps team. In order to do that, instead of passing the domain ENV into the service. We could overwrite the spec attribute after fetch

Start with the SwaggerUIBundle configuration and the dev-helper-initializer example, then compare the behavior with the draft PR at #9614. Trace how specs from urls, a URL, or a local path are fetched and determine where the requested overwrite configuration should be applied. Done means the configured JSON attributes are applied after fetching each supported spec source.
