Add native schema support for org.fugerit.java:fj-doc-base and org.fugeri.tjava:fj-doc-freemarker

What does this PR do?

I recently added to one of my project the native metadata needed for GraalVM :
https://github.com/fugerit-org/fj-doc/tree/main/fj-doc-base
https://github.com/fugerit-org/fj-doc/tree/main/fj-doc-freemarker

As for the "CONTRIBUTING" section, the metadata are mantained and tested direcly in my project repository, But as I understand a pull request is needed to be listed here https://www.graalvm.org/native-image/libraries-and-frameworks/

PS: This is my first pull request here, so I hope i filled it property. I tried to read the documentation and I hope I understood it properly.
PSS: Thanks a lot for your great work with GraalVM, we converted already a few production projects to AOT and we are very happy for the gain in

Hello, may I know if got something wrong about the pull request @fniephaus ?

As far as I have understood as we included in the project repository the native metadata, tests and so on are handled on our repository. Is it correct?

Thanks in advance.
