error when committing without tag

[thepercival]

Hello,

I have set "default_bump": false When I commit without a tag in the commit-message, an error returns when this action is executes: "Error undefined: No tag found in ref or input!" ncipollo/release-action@v1 needsa ref or input, but "github-tag-action" should not throw an error when "default_bump": false imho. Best to just do nothing, because this is what you want when "default_bump": false.

thanks in advance for looking at this.
