fix(maven): Include manifest in source JAR process

* Updated the `pom.xml` to configure the `maven-source-plugin` to use the default manifest file.
* Added the `<useDefaultManifestFile>` flag and specified the path to the default manifest file (`MANIFEST.MF`) within the `configuration` block of the plugin.

This also fixed an issue in the Maven build process where the manifest file was not being included in the source JAR created by the `maven-source-plugin:jar-no-fork` goal.
