Improvement: Architecture process documentation have multiple issues

### What

There are some review finding for
https://github.com/eclipse-score/process_description/blob/main/process/process_areas/architecture_design/architecture_concept.rst

- Dynamic Architecture is not inside a need? Feature and Component level
- SW Module View, see comment above, same here, what is the difference, really needed?
- There is a C++ shown in Component interface 1, some explanation, what is with Rust?
- Platform View, statement may no correct any more, after DDR-5, is agreed, Platform Architecture Work Product
- The architecture meta model is duplicated here, as in process folder? Also attributes, may better to link it?

That should be fixed.
