document that node.js is required to run drizzle-kit

Hi.

I just noticed that drizzle-kit fails with seemingly irrelevant error messages if I don't have node.js installed.

(this is the message that I got)

```
$ bun drizzle-kit push
No config path provided, using default 'drizzle.config.ts'
Reading config file '/path/to/drizzle.config.ts'
require() async module "/path/to/drizzle.config.ts" is unsupported. use "await import()" instead.
error: "drizzle-kit" exited with code 1
```

Is it possible to state that node.js is required to run drizzle-kit? maybe in [gotchas](https://orm.drizzle.team/docs/gotchas)?
