test: remove Yarn Modern config comments

[MikeMcC399]

Situation

Due to a bug yarnpkg/berry#1463 in Yarn Modern, any update to the version of Yarn Modern causes the config file yarnrc.yml of the two Yarn Modern examples to be re-written with comments removed.

Change

Execute:

./scripts/update-cypress-latest-yarn.sh

to allow Yarn Modern to reformat yarnrc.yml

---

Note

Low Risk
Comment-only edits in example Yarn config; no runtime, security, or dependency behavior changes.

Overview
Removes the inline comment on npmMinimalAgeGate in examples/yarn-modern/.yarnrc.yml and examples/yarn-modern-pnp/.yarnrc.yml, leaving the value as 7d with no behavior change.

This matches how Yarn Modern rewrites .yarnrc.yml when the toolchain is updated (see yarnpkg/berry#1463), so the example configs stay stable after running the Cypress/Yarn update script instead of churning on comment removal.
