Part of #9691

The apache project directory https://projects.apache.org lists all apache top level projects

To populate https://projects.apache.org/project.html?datafusion appropriately, we need to create an XML file with the project description

Describe the solution you'd like

Create a DOAP file for DataFusion following the directions of https://projects.apache.org/create.html

Describe alternatives you've considered

I think we should put the RDF file into the datafusion repository

Additional context

We can use the one from Arrow as inspiration: https://github.com/apache/arrow-site/blob/main/arrow.rdf
