fix: drizzle add-on outdated and broken

[w3cj]

Encountered several issues when trying to create an app with the drizzle add-on.

• Upgrade dependencies in frameworks/react-cra/add-ons/drizzle/package.json.ejs
  • drizzle-orm / drizzle-kit versions listed were over 1 year old (they have not reached v1 yet, so need to install latest minor version directly)
  • better-sqlite3 was 3 versions behind (resulting in node-gyp build error)
  • @types/mysql2 is not necessary
  • tsx is not necessary
• Choosing drizzle / mysql during setup would result in a package.json JSON parse error, the changes provided here fix this Errors were encountered during the creation of your app error
• Uses latest syntax in drizzle schema file (remove duplicate column names frameworks/react-cra/add-ons/drizzle/assets/src/db/schema.ts.ejs
• Tries to load .env.local first before .env in frameworks/react-cra/add-ons/drizzle/assets/drizzle.config.ts.ejs
  • Similar to fix: drizzle config not loading .env.local #247 but with fallback
  • Fixes Drizzle SQLite Generator is broken #249
• Update db connection file frameworks/react-cra/add-ons/drizzle/assets/src/db/index.ts.ejs
  • Remove dotenv config (tanstack start does this automatically)
  • Simplify creation
    • no need to directly create connection of each type
    • just pass in connection string to drizzle
