Respect Java remote debugging setting precedence when both debug modes are enabled

[Copilot]

When both enableRemoteDebugging and enableJavaRemoteDebugging settings are enabled, invoking "Start Remote Debugging" on a Java function app fails with a Node.js-specific error instead of delegating to the Java debugging flow.

Changes

Modified startRemoteDebug() to check runtime and delegate to Java debugging when appropriate:

// Check if Java remote debugging is enabled and if this is a Java function app
const isJavaRemoteDebuggingEnabled: boolean = !!getWorkspaceSetting<boolean>('enableJavaRemoteDebugging');
if (isJavaRemoteDebuggingEnabled) {
    const appSettings: StringDictionary = await siteClient.listApplicationSettings();
    const workerRuntime: string | undefined = appSettings.properties?.[workerRuntimeKey];

    // If this is a Java app, delegate to Java remote debugging
    if (workerRuntime?.toLowerCase() === 'java') {
        return await remoteDebugJavaFunctionApp(context, node);
    }
}

This ensures Java function apps use the Java debugging flow (which prompts for configuration changes) rather than failing with the Node.js-only error message.

This section details on the original issue you should resolve

<issue_title>Fail to execute "Start Remote Debugging" action for Java function app</issue_title>
<issue_description>OS: Win11
Build Version: 20251218.1

Repro Steps:

1. Enable the setting "Azure Functions: Enable Java Remote Debugging" and "Azure Functions: Enable Remote Debugging".
2. Right click one Java function app -> Select "Start Remote Debugging".
3. Check whether a confirmation dialog pops up.

Expect:
A confirmation dialog pops up.

Actual:
An error occurs.

More Info:

1. Just enable setting "Azure Functions: Enable Java Remote Debugging", the action "Attach Debugger" instead of "Start Remote Debugging" appears.
2. Just enable setting "Azure Functions: Enable Remote Debugging", the action "Start Remote Debugging" appears.

Comments on the Issue (you are @copilot in this section)

@motm32 We want to always respect the "Azure Functions: Enable Java Remote Debugging" over the "Azure Functions: Enable Remote Debugging" if it is a Java app and both settings are enabled.
