Check if all relevant options can be set via `sentry.properties`

### Description

We found some options (`send-default-pii` and `max-request-body-size`) that weren't parsed from external options (`sentry.properties`) and thus couldn't be configured for our Sentry OpenTelemetry Java Agent when using auto init.

We should investigate whether there's more options that should be configurable through `sentry.properties` but currently aren't.

首先稽核用於 sentry.properties 的選項解析，並將其與 Sentry OpenTelemetry Java Agent 支援的選項進行比較，包括 send-default-pii 和 max-request-body-size。完成的標準是：每個相關選項都可以透過 sentry.properties 進行設定，或被明確標示為不支援。
