make docker image for generating swagger

Summary

make docker image for generating swagger

Problem Definition

To generate integrated swagger in local, we need to install nodejs, yarn, protoc.
This is inconvenient because the version should be matched and local management is required.

I've failed before to implement it.
In osmosis case, when the new commit is added in main branch, the ci detect it automatically and register new PR if the difference is existed. I think it's good. But in this case we can miss why the swagger should be changed, and we maybe cannot know which change do effect.
So I think it's necessary to provide an environment where swagger can be changed right in the PR that needs to be changed.
