[Feature]: Make it easier to add documenation

[bikash119]

Problem

While working on the issue #1623, a few issues I encountered:

• As we have contributing docs for compoenents like backend, gateway, I couldn't find contributing docs for documents.
• The setup.py doesn't have mkdocs dependencies. A new contributor need to install the dependencies based on the failure message from mkdocs build command.

Solution

pip install -e .[docs] should install all the required dependencies for someone to build mkdocs.

Workaround
