cli: templatise tailwind and hardhat config

[technophile-04]

Description:

• templatise tailwind light and dark theme
  • this allow people to give SE-2 colors of their choice
• allow importing more stuff in hardhat.config.ts
  • Since hardhat requires something to be present in hardhat.config.ts for example plugins
  • another example is exposing tasks

Test:

1. use latest cli changes

yarn dev

2. Create a test instance:

yarn cli ../test-my-new-extension -e technophile-04/tailwind-hardhat-tasks-extension

I have created technophile-04/tailwind-hardhat-tasks-extension this extension which uses hardhat tasks and updates tailwind theme.

3. Go to directory :

cd ../test-my-new-extension

4. To check hardhat tasks:

cd packages/hardhat && yarn hardhat sayHello

^ the above should pring "Hello, World!"

5. Checkout the theme by doing yarn start
