Update yarn to latest stable version

[mchv]

What does this change?

This update yarn from 1.22.17 to the latest stable version 4.2.2.

There are a few noteworthy changes:

Adding the range for react-dom and react dependencies

The parsing of version dependency since yarn 2.x is more strict, which means the react and react-dom alias package needs an additional range to work (preact issue about it)

Removal of yarn-duplicate

The yarn-duplicate package is not necessary anymore, and has been replaced by the native dedupe command:

• commit f7abd45
• commit b8b0617
• commit 71195d9

When executing yarn install a few warnings are now displayed

The associated changes do not address them, but with the associated changes it should be easier to update packages to address them (for instance updating jest and ts-jest seems sensible and not too difficult)

In order to retrieve the right version of yarn, it is now recommended to use corepack, rather than
This is very similar to that change in dotcom-rendering:

• commit c63df94

Upgrade of node version

However for the right yarn version to be picked up, un upgrade to the latest 18.xx node version was needed (see pnpm/pnpm#7724), otherwise yarn version is not found:

And yarn install fail miserably:
