Review and update docker command in website setup

[nithinkodadhavadee]

Describe the problem

I was trying to build this site locally and faced issues with the command make setup. I am new to docker so I could not understand the error that I got.

this is the error I got:

touch .env
make clean
make[1]: Entering directory '/home/somanna/Scripts/flutter/website'
rm -rf _site .jekyll* src/.jekyll* *.log tmp .dart_tool
make[1]: Leaving directory '/home/somanna/Scripts/flutter/website'
docker-compose build --no-cache site
make: docker-compose: No such file or directory
make: *** [Makefile:62: setup] Error 127

Expected fix

I wonder if docker-compose can be replaced with docker compose as the earlier one is no longer available. I have the necessary changes, so I guess I can create a pull request.

Additional context

after a million Google searches later I stumbled upon this post from starkoverflow which says that docker-compose has been deprecated so I am supposed to use docker compose instead. I made a few changes to the makefile, removing dashes from docker-compose to make it docker compose. Now I can successfully build the site and use the docs.
