Make minified Docker image

[filipopo]

Is your feature request related to a problem? Please describe.
I believe the Docker image over at https://hub.docker.com/r/swacli/static-web-apps-cli is bloated and takes too long to pull since it contains full development environments for several programming languages

Describe the solution you'd like
To add tagged versions of the image with the environment you'd like to be built in or the lack of any for a minified image at https://hub.docker.com/r/swacli/static-web-apps-cli/tags

Describe alternatives you've considered
I suppose the alternative is to make my own minified node container with npm install -g @azure/static-web-apps-cli
