In #1369, I mistakenly replaced the hash-bang lines in the two new
scripts with `#!/bin/sh`, missing that both files contain the Bash'ism
`[[`. Symptom as per
https://github.com/actions/checkout/actions/runs/5200323109/jobs/9378889172?pr=1369#step:12:5

    __test__/verify-sparse-checkout.sh: 58: [[: not found

Let's change those hash-bang lines back to `#!/bin/bash`.

* update workflows

Setting the `show-progress` option to false in the `with` section of the
workflow step will cause git fetch to run without `--progress`.

The motivation is to be able to suppress the noisy progress status
output which adds many hundreds of "remote: Counting objects: 85%
(386/453)" and similar lines in the workflow log.

This should be sufficient to resolve #894 and its older friends,
though the solution is different to the one proposed there because
it doesn't use the --quiet flag. IIUC git doesn't show the progress
status by default since the output is not a terminal, so that's why
removing the --progress option is all that's needed.

Adding the --quiet flag doesn't make a lot of difference once the
--progress flag is removed, and actually I think using --quiet would
suppress some other more useful output that would be better left
visible.
