Build/Test Tools: Update 3rd-party GitHub Actions.

This updates all 3rd-party GitHub actions to their latest versions. The following actions were updated:
- `actions/cache`
- `actions/checkout`
- `actions/setup-node`
- `codecov/codecov-action`
- `shivammathur/setup-php`
- `slackapi/slack-github-action`

In the latest version of `actions/checkout` (`4.0.0`), a new input was introduced to control the output of command progress. This change uses this new `show-progress` input to turn off displaying progress by default. Progress will be shown when a workflow is run with debug mode enabled, just in case it contains helpful information.

Props johnbillion, desrosj.
