[Tooling] Update GitHub Actions

[iangmaia]

Reference: p7H4VZ-59z-p2

WordPress Android doesn't use one of the GitHub Actions about to have its older versions deprecated as actions/upload-artifact, actions/download-artifact or actions/cache, but I used this opportunity to upgrade actions/checkout and gradle/actions/wrapper-validation.
