We should only pass the VERSION option if we have a value to pass.
Fixes warnings like the one below when using CMake 3.31:
CMake Warning (dev) at cmake/QtPublicSbomAttributionHelpers.cmake:511
(cmake_parse_arguments):
The VERSION keyword was followed by an empty string or no value at
all.
Policy CMP0174 is not set, so cmake_parse_arguments() will unset the
arg_VERSION variable rather than setting it to an empty string.
