Unable to access swagger API after enabling prefix routing

Bug description

I'm having an issue with accessing the /api/v1/_openapi endpoint. It looks like it redirects to /api/v1/_openapi but it should be going to /prefix/api/v1/_openapi it would be nice to expose the swagger config so we can do something like this.

OPENAPI_SWAGGER_UI_CONFIG = {
    "url": "/prefix/api/v1/_openapi"
} 

Not sure if anyone else has seen this issue or is able to replicate it.

To replicate the issue just set

SUPERSET_APP_ROOT = "/prefix"

then attempt to go to /prefix/swagger/v1
