build: separate yarn and pnpm maintenance scripts

[MikeMcC399]

Issue

The maintenance scripts, which update the Cypress examples, combine pnpm and Yarn actions in one script. As the number of examples has grown to cover different package manager variants for Yarn and pnpm, this has become less flexible to maintain.

Changes

The contents of the scripts

• scripts/update-cypress-latest-other.sh and
• scripts/check-package-managers-other.sh

are split into separate scripts for Yarn and pnpm respectively.

The overall function remains the same and the documentation docs/MAINTENANCE.md needs no changes.

Verification

On Ubuntu 22.04.04 LTS with Node.js 20.12.0 LTS, execute:

git clean -xfd
npm ci
npm run update:cypress

and confirm success.
