Add Discoverability For F5'ing Python and Node projects

[alexyaang]

This was something we discovered during developing the .NET ambient task feature. Addressing this issue will allow our scaffolding command to be more discoverable.

Reproduce steps:

When you F5 on a python / node file, you do not see the debugger from our extension.

However, you do see our debugger while F5'ing a C# file, you do. (This is added by the .NET SDK Build PR microsoft/vscode-docker#3960)
