Fix: Updated PackageSupplier to type Organization for JAR files

[harippriyas]

Issue:
The PackageSupplier and PackageOriginator are set to type 'Person' for JAR files. For example:

PackageName: jackson-annotations
SPDXID: SPDXRef-Package-java-archive-jackson-annotations-55544ed7d2a352e0
PackageVersion: 2.9.10
PackageSupplier: Person: FasterXML
PackageOriginator: Person: FasterXML

Fix:
Updated to set the type as 'Organization' if vendor is specified in the metadata file of the JAR.

Result:

PackageName: jackson-annotations
SPDXID: SPDXRef-Package-java-archive-jackson-annotations-55544ed7d2a352e0
PackageVersion: 2.9.10
PackageSupplier: Organization: FasterXML
PackageOriginator: Organization: FasterXML

As we discussed, I think this is a good change, could you consider adding a test so we don't regress here?

The tests were there, the file was not checked in. Can you please re-trigger the workflow to run the tests? Thanks
