Use the environment variable SIMPLEQUEUE to use either Queue or SimpleQueue Anonymine used SimpleQueue instead of Queue on SerenityOS as a workaround for https://github.com/SerenityOS/serenity/issues/19118 and https://github.com/SerenityOS/serenity/issues/22334 This is no longer necessary since https://github.com/SerenityOS/serenity/commit/f972eda7ed812deb77bcbe564bc8fc422b029399 This feature will be removed in the next commit.
