Fix Rosenbrock docstrings in OrdinaryDiffEq.jl

- Remove duplicate docstrings from generic_rosenbrock.jl
- Consolidate all Rosenbrock method docstrings in algorithms.jl
- Add proper citation information to all Rosenbrock methods
- Update citations for Rodas5P (BIT Numerical Mathematics 2023)
- Add JuliaCon proceedings citations for Rodas5Pr, Rodas5Pe, Rodas23W, Rodas3P
- Ensure consistent formatting with OrdinaryDiffEq.jl documentation standards

This resolves the issue where docstrings were duplicated between two files
and adds missing citation information that was only present in comments.
