Add Autocomplete and Syntax Highlighting (#109)

* Add basic syntax highlighting and autocomplete

* Add some more documentation

* Added keywords

* Add autocomplete for all groups based on variant + Fix bug where variables in inner scopes didn't work

* Add for statements + Fix function names and name declarations coming as their own suggestion

* Migrate to `@sourceacademy/autocomplete`

* Update `ts-node` to `tsx`

* Use `.kind` instead of `.constructor.name` to allow function name terserification

* Fix the step limit

* Refactor type narrowing

* Remove unused code

* Fix some bugs (prelude functions not working + `==` not working for expanded equality + mismatched name in Python 4 stdlib)

* Add explicit types for every evaluator + fix test cases for parser

* Fix bug regarding missing py_s1_constants.json

* feat(conductor): add per-evaluator autocomplete and syntax highlighting

the correct variant number and evaluator name, so the runner emits a
unique ace mode id (ace/mode/PyCseEvaluator{1..4}) per bundle.

* style: format PyCseEvaluator.ts

* Add `range` support + Add test cases

The autocomplete keyword lists were wrong on two counts:
- is/global/nonlocal/pass are meant to be introduced at chapter 3, same
  as while/for/break/continue - but is was hardcoded permanently
  illegal, and global/nonlocal/pass were hardcoded permanently legal,
  in every chapter.
- True/False/None weren't classified at all, so they rendered as plain
  identifiers. Ace's own stock Python highlighter (which this file is
  adapted from) colors them as constant.language, matching how other
