[VSC-1753]Add notification system for pre-releases campaigns

[radurentea]

Description

This pull request introduces a pre-release notification system to promote the new ESP-IDF Extension setup experience with the ESP-IDF Installer Manager (EIM). The notification includes comprehensive telemetry tracking, campaign-based targeting, and full internationalization support.

Pre-release notification system implementation:

• src/preReleaseNotification.ts: Added a new notification system that displays a targeted campaign message to promote the pre-release version featuring the new EIM setup experience. Includes campaign-based tracking to ensure the notification is shown only once per campaign, telemetry integration for user interaction analytics, and proper handling of user responses (try pre-release, learn more, dismiss).
• src/extension.ts: Integrated the pre-release notification into the extension activation flow, positioned after the changelog viewer to ensure proper initialization sequence.
• src/config.ts: Added configuration constants for the pre-release notification system, including the campaign key for EIM setup 2025 and storage key for tracking shown campaigns.

Telemetry and analytics integration:

• src/preReleaseNotification.ts: Implemented comprehensive telemetry tracking for all user interactions including notification display, button clicks (try pre-release, learn more, dismiss), and campaign identification. Uses the existing telemetry infrastructure with event name preReleaseNotification and properties for campaign tracking, action identification, and extension version.

Localization and internationalization support:

• src/preReleaseNotification.ts: Added full localization support using VS Code's l10n.t() system for all user-facing strings including the main notification message, button labels, and instruction text.
• l10n/bundle.l10n.es.json, l10n/bundle.l10n.pt.json, l10n/bundle.l10n.ru.json, l10n/bundle.l10n.zh-CN.json: Added comprehensive translations for the pre-release notification in Spanish, Portuguese, Russian, and Chinese, including the main promotional message about EIM, button labels ("Try New Pre-Release", "Learn More", "Not Now"), installation instructions, and confirmation dialogs.

Thanks for the implementation.
One think I noticed is if the user enters the "Learn More" option the notification is gone and the user cannot get back to it. Can we isolate that button so it does not erase the notification? I believe the behavior of clearing the notification on the "try" and "not now" button is fine, just the learn more would be nice to keep the notification until the user selects one of the other 2 buttons.

I couldn't find a way to do this within VS Code API, however, we could add a timer, so after the "learn more" button is pressed we can wait for a time and re-redisplay the notification. We can agree on the amount of time if you think this would be a better experience than the current one (closing the notification after any button press).
