[next-v5] Allow Swagger file to be set locally via docker

[tokidoki11]

Description

I only run docker swagger v5 (alpha96) without building the react

in version 4 you can specify env variable to set the definition file location
docker run -d -p 80:8080 -v $(pwd):/tmp -e SWAGGER_FILE=/tmp/swagger.json swaggerapi/swagger-editor

Currently I think it only support default file definition by building react yourself via .env file

Describe the solution you'd like

allow SWAGGER_FILE env variable to setup default file on docker run

Describe alternatives you've considered

nice I was wandering about the same thing.
In fact, I was expecting that it could read it from an environment variable in the docker container.

same here.... loading the file every time in editor and download it & upload up to UI is a boring task
