commit f5d09d8be2adb4d899973dc7883cb742f809cdf1
Author: Tobias Bouschen <to...@googlemail.com>
AuthorDate: Tue Feb 9 15:05:48 2021 +0100

    Only try to publish results if there are any changes
    
    Adjusts the deploy action to only try to commit and push if there are
    any staged changes. This avoids the action "failing" if there is nothing
    to commit.
