v0.8.0 🦝 : test, test, test 💗

💗 Happy with cffu! 🦝 and be a "shifu"~ 😆

☔️ Test

• 💪 test case: check MinimalStage status of Cffu/CompletableFuture 🙌
• 💪 test case: check thread/executor for *Async operation of CompletableFuture/Cffu 🙌
• test: output env infos when test 👀
• reduce test thread pool size 📉
• use CompletionStage.await() instead of Future.get() if in Kotlin coroutine

📚 Documentation

• add overview.html for javadoc
• fix wrong external link of javadoc(java std lib, jsr305)
  by setting source option of javadoc to 19
• improve javadoc of Cffu.state()/CffuFactory#asCffu/CffuFactory.AsyncPoolHolder
• fix wrong section comments of CffuFactory 📚
• place @SuppressWarnings("unchecked") as last annotation ✋
  because it's least informative for user

🚜 Chore/Bulid

• add kotlin.compiler.apiVersion = 1.5 🍩
  make sure works for older kotlin version
• update CI java 20 version to release from ea ☕️
• add java 21 ✨ to CI
