### Describe the Bug

I wanted to contribute to the project so I followed the steps in `CONTRIBUTING.md`.

According to the docs, I'm supposed to use Node `18.13.0`.
https://github.com/drizzle-team/drizzle-orm/blob/main/CONTRIBUTING.md#-installing-node

```
nvm install 18.13.0
nvm use 18.13.0
```

However, in the [pnpm build step](https://github.com/drizzle-team/drizzle-orm/blob/main/CONTRIBUTING.md#-building-the-project), I'm getting the following error:

```
TypeError: os.availableParallelism is not a function
```

According to the [Node.js docs](https://nodejs.org/api/os.html#osavailableparallelism), the `availableParallelism` function had been added in version `18.14.0`, so it's not available in `18.13.0` yet.

### Fix:
Use Node.js `18.14.0` instead of `18.13.0`.
`pnpm build` works without any issue on `18.14.0`.

### Change needed in `CONTRIBUTING.md`:

Replace this:

```
nvm install 18.13.0
nvm use 18.13.0
```

With this:
```
nvm install 18.14.0
nvm use 18.14.0
```
