test: complete cypress@15.16.0 update

[MikeMcC399]

Situation

Running the script update:cypress makes changes that Renovate can not cover.

• Workflow .github/workflows/example-install-only.yml uses a pinned version cypress@15.12.0 that doesn't get automatically updated.
• The Yarn 4 yarn set version command causes yarnrc.yml to be reformatted. This is a known bug with resolution delayed until Yarn 6.

Change

• Update workflow .github/workflows/example-install-only.yml to use the pinned version cypress@15.16.0
• Commit the reformatted results of yarnrc.yml after running the Yarn Modern yarn set version command

Note

Low Risk
Example workflow and Yarn config formatting only; no application, auth, or runtime behavior changes.

Overview
Completes the Cypress 15.16.0 rollout for repo maintenance that Renovate does not handle automatically.

The install-only example workflow now pins npm install cypress@15.16.0 instead of 15.12.0, keeping CI aligned with the rest of the examples updated by update:cypress.

Yarn Modern example .yarnrc.yml files pick up an extra blank line after npmMinimalAgeGate from yarn set version reformatting (no policy change to npmPreapprovedPackages).
