[Bug]: failure to handle non-numeric workspace names in event listeners

[nikitax44]

Traceback (most recent call last):

    return int(ws)
           ^^^^^^^
ValueError: invalid literal for int() with base 10: 'default:(1 1)'

cause: fabric listens for event::workspace insead of event::workspacev2 to handle workspace events (and also createworkspace and destroyworkspace instead of v2 versions).

the old events do not contain workspace_id, only workspace_name.

see fabric/hyprland/widgets.py:157
