wifi: rtw89: wow: Add Basic Rate IE to probe request in scheduled scan mode

In scheduled scan mode, the current probe request only includes the SSID
IE, but omits the Basic Rate IE. Some APs do not respond to such
incomplete probe requests, causing net-detect failures. To improve
interoperability and ensure APs respond correctly, add the Basic Rate IE
to the probe request in driver.
