Update documentation for Swagger-CodeGen Tool in the official web page at https://swagger.io/

[LazaroOnline]

The documentation for the swagger tools is way outdated:

• swagger-editor: https://swagger.io/docs/open-source-tools/swagger-editor/
• swagger-ui: https://swagger.io/docs/open-source-tools/swagger-ui/usage/installation/
• swagger-codegen tool: https://swagger.io/docs/open-source-tools/swagger-codegen/

It can be updated or replaced with the info from the respective repository's Readme since it is up-to-date in GitHub (but not in your own official webpage):

swagger-api/swagger-editor
swagger-api/swagger-ui
swagger-api/swagger-codegen

The problem is that I was trying to use the swagger-codegen tool and went to the official documentation here and followed those steps only to realize that is using a waaay older version of the tool (v2.3.0 with Java 7) that doesn't even support the new specs, so after loosing some time trying to make that work, I latter realized those docs are outdated and the real latest version was somewhere else here:
https://github.com/swagger-api/swagger-codegen/blob/master/README.md

Now I can't trust anything from https://swagger.io since it has been un-maintained for 7 years now (v2.3.0 was released in 2017).
Also this was reported in the issue #353 and I even created a pull request to fix it here, but it has been closed as "not-needed" (???), I believe it was a mistake, so please, can you re-check that so the page is effectively updated? I would appreciate it. Thanks.
