🚀 [Feature]: contrib/swagger.go exposes internal adresses. There should be a possibility to self-host

[knollet]

Feature Description

Self host swagger to be able to use this even without internet access and to not expose internal addresses.

contrib/swagger
defines a struct Config, which could include an optional field for an address where swagger is hosted.

Currently external default addresses (unpkg.com) are hardcoded here:
https://github.com/go-openapi/runtime/blob/master/middleware/swaggerui.go
There's an optional SwaggerUIOpts.Template parameter which is not settable through contrib/swagger.

It would be a plus to have an example as to how clone swagger into my project and how to configure fiber to use that.
