fix: support environment variable expansion

[Esirei]

This fixes an issue where the usage of dotenv sets unexpanded VITE_* environment variables in the process.env which end up being prioritized here and are therefore skipped here.

Given the example .env below, usages of import.meta.env.VITE_APP_NAME will now properly output Laravel instead of ${APP_NAME}

APP_NAME=Laravel
VITE_APP_NAME=${APP_NAME}

I released laravel-vite@0.0.21 with that fix. 👍
