Enable ANSI colors by default when starting the app with mix_task

[macabeus]

As far as I know, the built-in VS Code debug console supports all ANSI color features.

But when running the application using the mix_task task, it's disabled.

It would be good if it's enabled by default.
It avoids confusion and the need to explicitly turn it on from the application code.

How to reproduce

1 - Clone this repo:

git clone [email protected]:macabeus/vscode-elixir-ls-issue.git

It's a dummy Elixir project with .vscode/launch.json configuration to start with mix_task

2 - Open the project with VS Code

3 - Run the debugger:

4 - You'll can see from the debug console that the ansi_enabled is disabled, and there are no ANSI colors:

5 - But the VS Code debug console supports ANSI colors. If we uncomment the line from lib/application.ex, you'll can see it working as expected:

Last time I checked on VSCode 1.85 it looked bad in both Debug console and Test results thought they supposedly added support in 1.80. On 1.90 it looks OK. Thanks for the repro
