Based on insights gained from reviewing conventions in #9815 with @jtmcg, I'm renaming this testscript to keep consistent with `gpg-key`, `label`, `ssh-key`, etc.
As this testscript creates a Bash-based script extension, the testscript should be skipped if it isn't on the path and executable.
Ideally, we would refactor this test to isolate that portion of the tests OR switch to a Go-based extension that can be compiled and run everywhere.
