Subject: [PATCH] fix: use bash arrays for BUILD_ARGS and LABELS to handle
 values with spaces

Labels like org.opencontainers.image.description="Python GitHub Runner"
contain spaces. Using unquoted string variables caused word-splitting when
passed to buildah, resulting in "accepts at most 1 arg(s), received 13".

Switch to bash arrays with proper quoting so values with spaces are passed
as single arguments.
