    sdk: invert logic for GIT_BRANCH and GIT_TAGNAME
    
    There is currently a logic error with generating the base feed string.
    
    In the scenario where the commit of a Tag match the latest commit of a
    stable branch, the stable branch have priority over the tag name.
    
    This results in generating SDK that actually target the branch instead
    of the specific tag.
    
    To fix this invert the logic and give priority to the tag name.
    
    Fixes: #18583
