React-admin: ra-core: Warnings due to deprecated requires referencing [email protected] package

[MiMo42]

At least ra-core package performs deprecated require calls.

See release notes for v4.8.0 of history package:
https://github.com/ReactTraining/history/releases

Accordingly we get warnings in the console:
Warning: Please use require("history").createHashHistory instead of require("history/createHashHistory"). Support for the latter will be removed in the next major release.
Warning: Please use require("history").createBrowserHistory instead of require("history/createBrowserHistory"). Support for the latter will be removed in the next major release.

Steps to reproduce:
Perform
yarn upgrade
to get the latest packages and load page.

Environment

• React-admin version: 2.8.2

Hi @fzaninotto, I had this issue which I was able to fix by updating the library.
Thanks for all your hard work with react-admin! It's truly inspiring 🙌
