Feat: Add Dockerfile for testing install.sh script on Ubuntu 24.04 (#1)

[Itz-Agasta]

Closes #1

This commit introduces a Dockerfile to facilitate testing the install.sh script in a controlled Ubuntu 24.04 environment.
These changes ensure that the install.sh script can be tested in a consistent environment, avoiding issues related to different host system configurations.

Setup Instructions:

Build the Docker Image:

docker build -t xui .

Run the Docker Container:

docker run -it --name xuitest xui

Result:

Please let me know if you want to change or add anything to the PR. Also, I will be glad to add the Docker documentation to README.md., Or publish the Docker image into dockerhub. Just raise the issue and assign me.

Cheers 🥂
Have a great day!
