Change devcontainer.json to forward used ports for the project

[duduribeiro]

Motivation / Background

Currently the generated devcontainer.json file does not forward the ports required for the project, so you need to manually change it in order to access the project when running via Devcontainer.

This PR adds the required projects for the project.

Detail

Changed the devcontainer class to include the ports needed for the project and then puts it on the forwardPorts attribute on devcontainer.json

This isn't required. I can working and get post forwarded automatically by vscode without those changes. Why isn't it working for you?

[duduribeiro]

@rafaelfranca Vscode is not my main editor, so I use https://github.com/devcontainers/cli to start my devcontainer and then I connect to the container to edit my files there.

Also, when I use my VSCode I don't have an remote.autoForward ports enabled, so it does not work. I would say it would be better to have all explicitly forwarded ports in the devcontainer definition.

Also, other editors may not have auto forward feature. See that RubyMine's devcontainer does not have autoforward https://youtrack.jetbrains.com/issue/IDEA-324256

this is why I think it would be better to have the forwardPorts explicitly on the definition
