📜 Description

Renames the generic logging-integration opt-in from enableLogs to logsEnabled before the new API is released:

• Logback XML: <logsEnabled>true</logsEnabled>
• Log4j2 plugin attribute: logsEnabled="true"
• JUL LogManager: io.sentry.jul.SentryHandler.logsEnabled=true
• Spring Boot: sentry.logging.logs-enabled=true
• Timber constructors and property: logsEnabled
• Android Timber option: timberLogsEnabled
• Android Logcat option: logcatLogsEnabled

Java integrations expose state-oriented get...Enabled() and set...Enabled() accessors, which map to natural .logsEnabled, .timberLogsEnabled, and .logcatLogsEnabled property syntax in Kotlin. Samples, tests, API dumps, and option guidance use the renamed controls.

Legacy aggregate ExternalOptions.enableLogs detection remains unchanged because it exists only to warn about obsolete logs.enabled configuration. The Android manifest keys remain io.sentry.timber.logs.enabled and io.sentry.logcat.logs.enabled.

💡 Motivation and Context

logsEnabled describes state rather than an action and provides a consistent .logsEnabled property across Kotlin-native and Java-defined integrations.
