Fix: Handle TabClose event in ZenPinnedTabManager

This commit addresses a bug where the `TabClose` event was not being handled correctly by the `ZenPinnedTabManager`. This resulted in incorrect behavior when closing tabs, particularly in the context of multiple windows.

The following changes were made:

- The `TabClose` event is now handled explicitly within the `_onTabEvent` method.
- The `_removePinnedAttributes` method is called to remove any pinned attributes associated with the closed tab.
- The `_onCloseTabShortcut` method is updated to use `e.target?.closest("tab")` to ensure it targets the correct tab element.

This fix ensures that pinned tab attributes are properly removed when a tab is closed, preventing unexpected behavior and data inconsistencies.
