Wrong sleep configuration when adding configuration files for alpine container

[CrazySky2121]

For example we have docker-compose.yml file with alpine based web container.

When we use Remote-Containers: Add Development Container Configuration Files from docker-compose and choose web container we have created .devcontainer/docker-compose.yml with following content in command key:

# Overrides default command so things don't shut down after the process ends. command: sleep infinity

But Alpine doesn't support infinity arg for sleep command and therefore our container failed to run with exit code 1.
Instead of this following content must be in command for same behavior as infinity:

# Overrides default command so things don't shut down after the process ends. command: sleep 3600

Steps to Reproduce:

1. Setup latest Alpine Linux with docker-compose.yml
2. Run Remote-Containers: Add Development Container Configuration Files and choose from docker-compose.yml
