The minimum required shellcheck version treats paths with leading variables as starting from the script's current directory, so shellcheck is able to source all of these files without needing the extra directives: v0.7.2 - 2021-04-19 Changed * SC1090: A leading $x/ or $(x)/ is now treated as ./ when locating files Remove them to avoid future copy pasting and confusion that they are required. Because the paths weren't actually followed, they didn't have to be accurate and accepted any string to silence the warning.
