Updated quickstart.md to contemplate common issue

Issue Found

While trying to run the project I encountered an issue. There was no specification on the pnpm version and even though I had all the other versions correctly, I was getting the same constant error. 

The project requires specific versions of pnpm (9+?) as defined in the package.json, but when trying to install dependencies, I kept getting ERR_PNPM_META_FETCH_FAIL errors and broken lockfile warnings.

The root cause was a mismatch between my system's pnpm version and the one specified in the project.

Solution

Using nvm + corepack solved the issue. After fixing this on my end, I'm adding this documentation to improve experience!

'''
   corepack enable
   corepack prepare [email protected] --activate
'''

Helped me solve the issue.
