Docker container for local development of the site

[Murdock9803]

Description

Currently, the site requires specific versions of technologies such as hugo extended, GO, etc, to be able to develop locally by the contributors. This often creates problems in one or the other dependencies and the users face problem in developing the site locally.

Suggestion

Dockerization of the whole site will allow users to develop the site locally with just a single command, without even installing any specific versions of the dependencies. This will make the development process much faster.

Additional Context

The right directories can be containerized so that the contributors can directly see their changes being developed locally.
