feat(use-dataloader): add global onError handler

[chambo-e]

This will allow us to have a global handler for errors

If a onError handler is specified in a useDataloader it will override the one from the Provider

import { DataLoaderProvider, useDataLoader } from '@scaleway-lib/use-dataloader'
import React from 'react'
import ReactDOM from 'react-dom'

const failingPromise = async () => {
  throw new Error('error')
}

const App = () => {
  useDataLoader('local-error',  failingPromise,  {
    onError: (error) => {
      console.log(`local onError: ${error}`)
    }
  })
  
  useDataLoader('error', failingPromise)
  
  return null
}

const globalOnError = (error) => {
  console.log(`global onError: ${error}`)
}

ReactDOM.render(
  <React.StrictMode>
    <DataLoaderProvider onError={globalOnError}>
      <App />
    </DataLoaderProvider>
  </React.StrictMode>,
  document.getElementById('root'),
)
