[FEATURE]: Using bun as a cli runner

### Describe what you want

My vite project uses `import.meta.env` in many places, and the drizzle cli throws an error when run with node cjs, but if I force `bun -b` to run `drizzle-kit generate:sqlite` it doesn't throw an error but the cli will output the

```
drizzle-kit: v0.20.13
drizzle-orm: v0.29.3

No config path provided, using default 'drizzle.config.ts'
Reading config file './drizzle.config.ts'
0 tables

No schema changes, nothing to migrate 😴
```

I therefore recommend that drizzle-kit use bun as the runner by default, with the added benefit that cli no longer needs to transpile ts, and dotenv loading is automatic.
