Outdated maven dependency on thombergs.github.io/diffparser

[AdeshAtole]

This can be updated to use

        <dependency>
            <groupId>io.reflectoring.diffparser</groupId>
            <artifactId>diffparser</artifactId>
            <version>1.4</version>
        </dependency>

on thombergs.github.io/diffparser

It is little misleading.
