[Monorepo] Move bob build to build script (#3525)

## Description

When I tried to install _**GestureHandler**_ from newly created package, it fails with message:

```
command not found: bob
```

This PR moves `bob build` into `build` script (as it is already done in [Reanimated](https://github.com/software-mansion/react-native-reanimated/blob/30f397ff4851029ee10c39283b2893fb231af63e/packages/react-native-reanimated/package.json#L33)), so that `postinstall` no longer fails.
 
## Test plan

Generate new package and add it to newly created app.
