Local Install isn't initializing

Hello! I am trying to install a local version of the resource for an upcoming trip out of the country (so I will have fast and reliable reference resources) but when I follow the steps in the initial README, I am getting an error. I changed the name of .env.local.example to .env.local and updated the file with a personal access token I generated from my GH account with Public Repo access. Further, I have also installed yarn and node. When I run yarn dev, I am getting an error that starts with:

Browserslist: caniuse-lite is outdated. Please run:
npx browserslist@latest --update-db

and ends with:

error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

Problem; I am not experienced with Node, Yarn or most all of the other tools used to here to launch and make the local resource available. It seems like yarn has been updated to a newer version, and that may be blocking part of the issue. I have tried running the browswerlist update but that did not resolve the issue or remove this portion of the error message. Any assistance you can provide would be amazing!

Start with the initial README and the local setup using .env.local.example, then reproduce the failure with yarn dev. Check the reported Browserslist message and the command's final error output without assuming the update resolves it. Done means a documented local installation initializes successfully without exiting with code 1.
