ci: add ubuntu 24.04 to tested operating systems

[MikeMcC399]

Change

An Ubuntu 24.04 job is added to the workflow .github/workflows/example-basic.yml to demonstrate the capability of Cypress to run under this OS version. This is in addition to the Ubuntu 20.04 and 22.04 jobs in the workflow.

A timeout-minutes: 10 of 10 minutes is added to each of the jobs as documented in the README > Timeouts section. This is a best practice in any case and is added as a precaution due to the beta status of the Ubuntu 24.04 runner (see below).

Other workflows are not changed at this time.

Background

• Ubuntu 24.04 LTS was released on April 24, 2024.
• GitHub Actions has made an Ubuntu 24.04 LTS runner image available in the overview on GitHub Actions Runner Images using the YAML Label ubuntu-24.04. The Label ubuntu-latest remains equivalent to the earlier ubuntu-22.04.
• The beta release of the runner was announced on May 14, 2024 GitHub-hosted runners: Public Beta of Ubuntu 24.04 is available
• The Ubuntu 24.04 LTS runner image currently contains Google Chrome. It does not yet include Microsoft Edge or Mozilla Firefox browsers.

There is not yet a Firefox or Edge browser in the ubuntu-24.04 beta image, so at the moment it is just for preliminary use. I will leave this PR in draft status until the image is updated.

Ubuntu 24.04 is still not available with other browsers.

I would rework the workflow later and use a matrix setup, like now implemented in https://github.com/cypress-io/github-action/blob/master/.github/workflows/example-basic-pnpm.yml.
