🐛 Bug: Crash in --mode create if pnpm version mismatches

[JoshuaKGoldberg]

Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

When you run npx create-typescript-app --mode create ..., the CLI should create a new repository as long as you have Node.js and pnpm installed.

Actual

If your local pnpm version isn't the expected one:

   ERR_PNPM_BAD_PM_VERSION  This project is configured to use v8.15.4 of pnpm. Your current pnpm is v9.0.6

  If you want to bypass this version check, you can set the "package-manager-strict" configuration to "false" or set the "COREPACK_ENABLE_STRICT" environment variable to "0"

Additional Info

I'm not sure what the right resolution would be... changing the pnpm version to the user's? Prompting them to install a new one? Disabling strict pnpm version checks? ...?
