Support devcontainer to develop the documentation.

This is feature request can be categorized as enhancement, not exactly the problem solving here.

Describe the solution you'd like

Currently it requires user to set up the website documentation development environment on their local system.
This would be trouble, complexity, dependencies, for developers to start the documentation development to make contribution.
Once we provide the devcontainer, it would be much easier to start the development with using the same exact environment for all developers.
This would avoid the dependencies and possible platform problems for the doc development.

Good idea! Will you help to complete this feature? Or we can add a good first issue label to see if there're any volunteers?
