fix - Fixed printf command for "-"

---

We've fixed the printf command in the release making workflow that refused
to work because of the "-" prefix, even when double-quoted.

---

Before

Before the fix is done, it would print a bogus error message.

  - printf "- SHA256 sum of bskyid (Windows): "

bash: printf: - : invalid option
printf: usage: printf [-v var] format [arguments]

After

The modified printf command causes the quoted text to be printed correctly

  - printf -- "- SHA256 sum of bskyid (Windows): "

- SHA256 sum of bskyid (Windows):
