CI: Revert recent "show build commands on terminal" change (#2000)

GitHub Actions UI does not handle large amounts of console output with
collapsable `::group::` sections well.
For example, UI may truncate console output if a collapsable `::group::`
section gets too many log lines. In some cases, GitHub does not report
truncation at all, resulting in misleading console output. In other, UI
warns: "This step has been truncated due to its large size. Download the
full logs from the menu once the workflow run has completed."

This change reverts recent commit e5a66fc26d.
