fix: Rename Type::isUnKnown() to isUnknown() (#16292)

Summary:
Pull Request resolved: #16292

Rename the `isUnKnown()` method to `isUnknown()` to fix the typo (capital 'K' should be lowercase 'k'). This brings the method naming in line with other similar methods like `isUnscaledLongDecimal()`, `isOpaque()`, etc.
