Switch to own maintained version of swagger-ui (#1619)

Fixes #1412
Fixes #1516 

Since [swagger-ui-bundle](https://github.com/dtkav/swagger_ui_bundle) is
no longer maintained, I forked it under the spec-first organization as
[py-swagger-ui](https://github.com/spec-first/py-swagger-ui). This PR
updates connexion to use it instead.
