File I/O Instrumentation with OkHttp Cache enabled

### Problem Statement

When I enabled [caching]() in the OkHttp client and activated File I/O Sentry instrumentation, I observed that the `file.write` span always ends with a `deadline_exceeded` status. This occurs due to the way OkHttp's `DiskLruCache` manages the journal file internally - it keeps the *journalWriter* open until explicitly closed.

Sentry SDK: `8.13.2`
Sentry Gradle Plugin: `5.8.0`

### Solution Brainstorm

Ideally, we want the span to be properly closed each time cached data is flushed (written). Perhaps the Sentry SDK could handle this differently if the File I/O operation originates from the OkHttp cache. Alternatively, it would be beneficial if we could filter this span out, preventing its duration from contributing to the total `ui.load` time.

首先使用 OkHttp 快取和 Sentry File I/O instrumentation 重現問題，然後檢查 DiskLruCache journalWriter 的行為以及 SDK 檔案寫入 span 的生命週期。確認快取寫入在 ui.load 中的表示方式，並將完成定義為消除錯誤的 deadline_exceeded 狀態，同時不遺失有用的 File I/O instrumentation。
