[UI v2] feat: Updates combobox filtering logic for automations

[devinvillarosa]

1. Updates combobox to have developers to use our own filtering mechanism. When trying to integrate it with other data resources, it doesn't seem like we'll be using cmdk's built in filtering mechanics

2. Updates AutomationsSelectStateFields component to use our own filtering mechanism. Because there is no API support for filtering by _like name, opting to do filtering on the client side
