Add test generator (#1722)

* cleanup dev tooling
  * move all scripts into `bin/`
  * turn several scripts into Rust tests:
    * `check_exercises_for_authors.sh`
    * `count_ignores.sh`
    * `verify_exercise_difficulty.sh`
    * `lint_tool_file_names.sh`
    * `lint_trailing_spaces.sh`
  * remove several scripts:
    * `check_uuids.sh`:
      `configlet lint` covers that already
    * `ensure_lib_src_rs_exists.sh`:
      this is not an issue if exercise stubs are generated
    * `clean_topics_vs_practices.py`:
      applies undocumented standards (max 10 practice exercises per topic)
    * `fetch_canonical_data`:
      we now have the submodule for this

* cleanup documentation
  * remove generic instructions about WSL
  * merge `CONTRIBUTING.md` and `maintaining.md`
  * move contributing docs in `README.md` to `CONTRIBUTING.md`
  * outsource instructions for making good PRs
  * outsource instructions for installing Rust
  * steal beautiful `REAMDE.md` from Python track

* apply conventions and guidelines in a couple places
  where the new Rust tests found deficiencies

* replace Bash-based exercise generation with Rust-based one
  (deleting the related `util/` Rust crates)
  * can be used to sync with problem-specifications too
  * uses the Tera templating engine for customizable test generation
    inspired by the python track using Jinja for this purpose

* apply test generation to acronym exercise to validate MVP
