fix: add generator for Visual Studio Code launch configuration

[shazron]

Add a generator to generate the Visual Studio Code launch configuration for a Project Firefly app.
The launch configuration enables debugging of actions via wskdebug, using aio app run or aio app run --local

Closes https://jira.corp.adobe.com/browse/ACNA-712

Motivation and Context

• This is to replace the launch config generation in the @adobe/aio-cli-plugin-app plugin
• This generator is to be run when adding or deleting an action in the app plugin (added to the add action and delete action commands)

How Has This Been Tested?

npm test

@shazron what happens when action is deleted? Do we run add-vs-code-config generator without the deleted action details and it overwrites the current config?

The generation of the vscode config is determined by the manifest, which is loaded by the app config loader. So as long as the app config reflects the current state of the app, the generator will base it off that. This generator will overwrite the existing vscode config.
