Adding azure-linux OS support for docker-in-docker feature

[sireeshajonnalagadda]

Feature:
Docker-in-docker

Description:

Solves issue
This is to add support of azureLinux OS for docker-in-docker feature

Changes:
Modified install script to work both ubuntu/debian and azureLinux
Created scenarios to check for both moby true and false

Checklist:
Changes worked as expected

install.sh compatibility
Confirmed that install.sh continues to work correctly with non–azure-linux base images, specifically Ubuntu and Debian.

Cross-distro testing
Ran scenarios with Ubuntu, Debian, and Mariner base images to validate docker-in-docker functionality across multiple environments.

Azure Linux support
Verified that after adding the implementation for the azure-linux distro, dev containers can be successfully built and run using docker-in-docker.

Hey @sireeshajonnalagadda - thanks for the PR :)

In PR description:

Could you list the testing / verification that has been performed to confirm that docker-in-docker feature is still working as expected after the addition of azure-linux OS support?

In particular:

• Is install.sh working with other base image types (not just azure-linux?)
• is azure-linux working? / can we build a dev container using it with this feature?

This seems like a big change to a fundamental technology (install script for docker-in-docker) so want to make sure we're doing the right thing here.

Hi @sam-byng,
I have modified the description to make it clearer and more meaningful.
