Upgrade Whitehall's base image to use Yarn 4 [WHIT-1954]

Open eYinka opened this issue 2 months ago • 1 comments

The previous image uses an outdated version of Yarn (1.22.22). This commit has now upgraded the package to the latest stable version (4.10.3). We have also updated the cache folder config to follow the new method. See:
