Bump BOM versions and mark core dep optional

Updates the project to microsphere-spring-cloud 0.2.24 in parent references and refreshes README latest release numbers to 0.2.19/0.1.19. Also marks `microsphere-java-core` as an optional dependency in `microsphere-i18n-core` to avoid forcing it transitively.
