fix checkstyle: Update StandardStateMachineCallback.java (apache#2290)

During the compilation of your code, an informational message was displayed indicating an issue with the file /home/lzy/hugegraph/hugegraph-core/src/main/java/org/apache/hugegraph/masterelection/StandardStateMachineCallback.java at line 36. The specific problem was that the length of this line exceeded 100 characters, with a total of 101 characters.

To address this issue, I have made modifications to this class. I have split the originally long line into multiple lines to ensure that each line's length adheres to the coding standards' specified limits. This action not only aligns with the requirements of the code style, but also improves the readability and maintainability of the code.
