Closes #1040

This broke anyone currently using the action.

Error: trufflesecurity/trufflehog/main/action.yml (Line: 29, Col: 10): Unrecognized named-value: 'inputs'. Located at position 1 within expression: inputs.version

I don't really think that the image field accepts the Github's expression syntax. It pretty much broke the workflow that I'm using. (Like what @james-callahan stated earlier)

One alternative is to give a default value not as seen on line 9, but to set it on this current line. In which I don't really know how to do that from the expression documentation. So like in Javascript, you'd do:

${{ input.version || 'latest' }}

But I guess that would be impossible because the expression syntax treats || as an OR operator.

any idea when can we fix this?
