`statamic new` requires tty to run

[amiuhle]

I'm trying to create a new statamic site in an automated process using a docker image. It works using the -it flags when running the docker image, but without an interactive tty terminal, Statamic fails right after printing the title art:

In Process.php line 1023:

  TTY mode requires /dev/tty to be read/writable.

Statamic site generation should not require an interactive shell if the --no-interaction flag is passed from the command line.

Please provide a way for us to reproduce this, or feel free to open a PR.

Also, what does composer global show | grep prompts output?

Below is a docker demo image built with Nix.

It can be built using

nix build && docker load < result

When it's run using the -it flag, it works but the second line without -it fails with the error message above.

docker run -it -v .:/project statamic-demo-image
docker run -v .:/project statamic-demo-image

Also, what does composer global show | grep prompts output?

The output is

laravel/prompts                  v0.1.12

I found a way to reproduce this without a docker image, see my PR comment here: https://github.com/statamic/cli/pull/66#issuecomment-1814252732
