Render Rust API docs #627
Description
We can use cargo rustdoc to build a stand-alone documentation that can be integrated into the website similar to doxygen.
We cannot use the doc.rs project to autobuild the documentation as they use Ubuntu 24.04 and preCICE needed to be available in the Ubuntu archives.
