ref(logs): remove ExperimentalAttribute and Experimental type from SentrySdk

[Flash0ver]

Remove

• usages of [ExperimentalAttribute] from all Logs-APIs
• Experimental type from SentrySdk

Keep

• Experimental type on SentryOptions

Example

-#pragma warning disable SENTRY0001

 options.Experimental.EnableLogs = true;
 options.Experimental.SetBeforeSendLog(static log => log);

-SentrySdk.Experimental.Logger.LogInfo("message");
+SentrySdk.Logger.LogInfo("message");
HubAdapter.Instance.Logger.LogInfo("message");

-#pragma warning restore SENTRY0001

We think we are fine with the API shape, but still keep one Experimental (on SentryOptions) before we go officially stable.

---

Note

Removes experimental markers from Structured Logs APIs and replaces SentrySdk.Experimental.Logger with SentrySdk.Logger, updating adapters, samples, API approvals, and changelog while keeping SentryOptions.Experimental.

• API Changes (Structured Logs):
  • Remove ExperimentalAttribute from SentryLog, SentryLogLevel, and SentryStructuredLogger methods, and from IHub.Logger/DisabledHub.Logger.
  • Replace SentrySdk.Experimental.Logger with new SentrySdk.Logger; remove SentrySdk.Experimental type; update HubAdapter.Logger to use SentrySdk.Logger.
  • Retain SentryOptions.Experimental (e.g., EnableLogs, SetBeforeSendLog).
• Samples: Update usage to SentrySdk.Logger.* and adjust comments.
• Tests/Approvals: Update API approval baselines to reflect non-experimental symbols and new SentrySdk.Logger.
• Changelog: Add API Changes entry describing the de-experimentalization and SentrySdk.Logger switch.
