test: update Yarn Modern to 4.14.1

[MikeMcC399]

Situation

The currently configured Yarn Modern 4.13.0 is not compatible with the update to Node.js 24.15.0 LTS. Also the attempted Renovate update to Yarn 4.14.0 in PR #1725 failed for the same compatibility reason.

Yarn Berry 4.14.1, released Apr 17, 2026 resolves the incompatibility.

Change

In the example directories:

• examples/yarn-modern
• examples/yarn-modern-pnp

currently using Yarn Modern 4.13.0, execute:

yarn set version latest
yarn

to update and migrate to the latest Yarn Modern release Yarn Berry 4.14.1

This is beyond the scope of what a Renovate update could do.

Note

Low Risk
Low risk: changes are limited to example projects’ Yarn configuration and lockfile metadata, with no production/runtime code impacted.

Overview
Updates the examples/yarn-modern and examples/yarn-modern-pnp projects to use Yarn 4.14.1 (from 4.13.0) via packageManager.

Adds Yarn config in .yarnrc.yml to allow approvedGitRepositories and enable enableScripts, and regenerates yarn.lock to the newer lockfile metadata version.
