Possibility to pass global variables

[rin-st]

Slightly updated the code of #331 (I used the same branch), see difference in the 7f54b7d. And now in arguments we can use functions with global variables as parameters, for example

const description = ({solidityFramework}) => `Hello ${solidityFramework}`

To test
Read the example extension scaffold-eth/create-eth-extensions#104
Create the instance using hardhat or foundry

yarn cli -e https://github.com/scaffold-eth/create-eth-extensions/tree/pass-global-vars

Check Readme and page.tsx of the instance

@technophile-04 I hope this is what you expected to see when created #331
