Re-add Lombok step when packaging source files #703
Description
As part of the test framework update (#672), several changes were made to the pom.xml file
One of the changes was to remove a seemingly unnecessary line related to Lombok from the <build> section:
<sourceDirectory>${project.build.directory}/delombok</sourceDirectory>
With this line the *-sources,jar we upload to Maven contained versions of the source files generated by Lombok, and without it the *-sources,jar contains the versions of the files found here on Github. Although this difference doesn't affect the compiled code in the msal4j-x.y.z.jar that Maven would use as a dependency, it can affect any customer who may want to build the msal4j package from *-sources,jar, as they would need to also use Lombok to match what we put in the msal4j-x.y.z.jar
