`CLERK_FRONTEND_API` replaced by `CLERK_PUBLISHABLE_KEY`

The CLERK_FRONTEND_API environment variable was renamed to CLERK_PUBLISHABLE_KEY. You can visit your Clerk dashboard to copy/paste the new keys after choosing your framework. Make sure to update this in all environments (e.g. dev, staging, production). Note: The values are different, so this is not just a key replacement. More information.
