update GitHub actions to use equinix-labs

[displague]

Use latest equinix-labs published GitHub actions

GitHub actions ran successfully and setup and teardown worked great.

However, integration CI did not run cleanly for terraform apply so the test should not have been marked as successful.

This continue_on_error: true should be replaced with if: always() (or if: success() || failure() which is cancelable and could be used to skip the destroy step)
