chore(deps): update Java SDK to v8.30.0

[github-actions]

Bumps modules/sentry-java from 8.29.0 to 8.30.0.

Auto-generated by a dependency updater.

Changelog

8.30.0

Fixes

• Fix ANRs when collecting device context (#4970)
  • IMPORTANT: This disables collecting external storage size (total/free) by default, to enable it back
    use options.isCollectExternalStorageContext = true or <meta-data android:name="io.sentry.external-storage-context" android:value="true" />
• Fix NullPointerException when reading ANR marker (#4979)
• Report discarded log in batch processor as log_byte (#4971)

Improvements

• Expose MAX_EVENT_SIZE_BYTES constant in SentryOptions (#4962)
• Discard envelopes on 4xx and 5xx response (#4950)
  • This aims to not overwhelm Sentry after an outage or load shedding (including HTTP 429) where too many events are sent at once

Feature

• Add a Tombstone integration that detects native crashes without relying on the NDK integration, but instead using ApplicationExitInfo.REASON_CRASH_NATIVE on Android 12+. (#4933)
  • Currently exposed via options as an internal API only.
  • If enabled alongside the NDK integration, crashes will be reported as two separate events. Users should enable only one; deduplication between both integrations will be added in a future release.
• Add Sentry Metrics to Java SDK (#5026)
  • Metrics are enabled by default
  • APIs are namespaced under Sentry.metrics()
  • We offer the following APIs:
    • count: A metric that increments counts
    • gauge: A metric that tracks a value that can go up or down
    • distribution: A metric that tracks the statistical distribution of values
  • For more details, see the Metrics documentation: https://docs.sentry.io/product/explore/metrics/getting-started/

Bug: The updated Java SDK may enable metrics by default, but the Unity SDK does not explicitly disable it, potentially causing unintended data collection on Android.
_{Severity: MEDIUM}

Suggested Fix

Verify if sentry-java v8.30.0 enables metrics by default. If it does, explicitly disable the feature in the Unity SDK's Android configuration (e.g., in SentryJava.cs via setEnableMetrics(false)) to prevent unintended behavior. Consider adding a corresponding option to SentryUnityOptions.cs for user control.

Potential issue: The update to the `sentry-java` dependency is believed to enable the
Sentry Metrics feature by default. The Unity SDK's Android integration does not
explicitly configure or disable this feature in `SentryJava.cs` or
`AndroidManifestConfiguration.cs`. This is inconsistent with the established pattern of
explicitly disabling other Java SDK features like `setAttachScreenshot` and
`setEnableAutoSessionTracking`. If metrics are enabled by default in the Java SDK, this
omission could lead to unintended data collection, increased network traffic, and
potential performance impact for Unity applications on Android.
