Exit-Code: 1 add failure description

[james-luther]

How feasilbe is it to give a description on failure. For example, if exit-code: 1 is set, the action fails without any description as to what causes the failure. For pull requests a comment stating the cause would be extremely helpful.

Currently Trivy follows the UNIX philosophy of exit codes. A non zero exit code implies something "undesirable" happened.

The exit code is supposed to be set by the user, therefore writing logic to indicate what went wrong wouldn't be ideal as it is set by the user in the first place.

I never followed up, thanks! This was my assumption but wasn't sure if there was an option built into the action or no.
