Logs are now flushed on shutdown

[adinauer]

📜 Description

When SentryClient.flush is invoked (e.g. through ShutdownHookIntegration), we now also flush out logs.

💡 Motivation and Context

On application shutdown, pending logs were not being sent out, e.g. in the Logback sample.

💚 How did you test it?

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
