Possible readme improvement: Adding sqlite3 through npm if brew doesn't work out

[njaaan]

Hi,

when our team tried so set up the workshop project, several devs ran into an issue with the installation of sqlite3.
It might be that the suggestion in the readme, to install with brew (brew install sqlite3) is not working properly for some people on more recent macOS versions. On Ventura what worked for us was uninstalling the brew version and using npm instead:

npm uninstall sqlite3 (to get rid of the brew version)
sudo npm install sqlite3
npm install
npm start

I couldn't add a PR to include this into the readme, so I thought I'll add it as an issue for either people who have the same issue to find or for you to add it to the readme.

Thanks for the great workshop. :)
