ci: make yarn globally available and independent of `$BASH_ENV` (#28889) 

Previously, our yarn (which overwrote the pre-installed yarn on the
docker image) was only available through `$BASH_ENV` (as an exported
function). This caused it to be undefined for commands executed in other
shells (e.g. via Node.js' `child_process.spawn()` unless explicitly
configuring it to run with `bash`).

This commit fixes this by making our yarn version available globally via
a symlink (`/usr/local/bin/yarn`).

(This was accidentally broken in #28839.)
