2.3.2 - even simpler task(async () => {}) API

• Simplified the async arrow fn task() API to allow omitting the this param, e.g.
  myTask = task(async () => {}) (#477)
• The codemods mentioned in the 2.3.0 release have been updated to prefer this simplified syntax:
  • Convert @task decorator based APIs to the new async-arrow fn
    • npx machty-ember-concurrency-codemods async-arrow-task app/**/*.ts
    • npx machty-ember-concurrency-codemods async-arrow-task app/**/*.js
  • If you've used ember-concurrency-ts, run the following codemod to remove taskFor()
    • npx machty-ember-concurrency-codemods rm-ember-concurrency-ts app/**/*.ts
    • npx machty-ember-concurrency-codemods rm-ember-concurrency-ts app/**/*.js
