Allow ignored airthings_ble devices to be set up from the user flow

Every few days we get an issue report about a device a user ignored and forgot about, and than can no longer get set up. Sometimes its a govee device, sometimes its a switchbot device, but the pattern is consistent.

Allow ignored devices to be selected in the user step and replace the ignored entry.

Same as #137056 and #137052 but for airthings
