Automate examples update to latest Cypress version

[MikeMcC399]

Current situation

When a new version of Cypress is released, the examples are not automatically updated to use this version.

For examples based on npm technology, scripts/npm-install-examples.sh updates Cypress to the latest version. This can be invoked manually through npm run install-deps. The settings in .npmrc determine that an exact version number is used.

In previous PRs, for instance PR #747, examples based on the Yarn 1 (Classic) package manager and the pnpm package manager were updated manually and individually:

1. examples/start-and-yarn-workspaces was updated using:
   yarn upgrade-interactive --latest

2. examples/install-command was updated using:
   yarn add cypress -D

3. examples/basic-pnpm was updated using:
   pnpm update --latest

4. The run command in .github/workflows/example-install-only.yml run: npm i cypress@12.x.x was manually edited.

examples/v9 is frozen to use the last Cypress 9.x version (9.7.0) and is not expected to change.

Suggested improvement

Provide better automation for easier updates to Cypress latest version, consistently applied.

I have automated updating to Cypress latest in branch build/update-cypress-latest.

The changes are here. I will submit a PR once the backlog of open PRs has been reduced and after I have had the chance to test it a little bit more.

I replaced the original script since it wasn't a DRY (Don't Repeat Yourself) thing and instead I wrote a do-loop to go through the npm examples.
