/usr/bin/which: no gprintf error on every bash startup if gprintf is not installed

Expected Behavior

No error message should appear

Current Behavior

/usr/bin/which: no gprintf error on every bash startup if gprintf is not installed

Possible Solution

The issue is caused by [ -x "$(which gprintf)" ] && _printf_cmd=gprintf in vendor/github.com/erichs/composure/composure.sh line 61.
Changing the code to something like

```shell
    if [ -x "$(which gprintf)" ]; then
      _printf_cmd=gprintf
    fi 2>/dev/null
```

fixes the issue, but I don't whether I should report this to upstream.

@NariyasuHeseri Thanks for reporting this! I saw this bug yesterday but wasn't able to follow up until this morning. I'm going to reach out to erichs and make a PR upstream today. If it looks like they'll be slow to act, we might discuss reverting in the meantime.

As for you today, if this gets too annoying, you can switch to the newest release tag until we fix this. Thanks again!

Edit: this is an issue with tagging and erichs has disabled issues, limiting discussion needed to address this, so we just need to track commits instead.
