fix: complete language version IDs for all platforms (#350)

## Problem

`LANGUAGE_VERSIONS` only covered cpp and python. Several platform IDs
were wrong — CodeChef used `C++ 17`/`Python 3` (correct: `C++`/`PYTH
3`), USACO listed nonexistent c++20/c++23 options, and CSES only had
C++17.

## Solution

Verify every platform's submit page and update all language ID tables.
Add java and rust entries where supported, fix incorrect CodeChef and
USACO IDs, and expand CSES `CSES_LANGUAGES` dict with
C++11/C++20/PyPy3/Java/Rust variants.
