Fix: Incorrect warning for nRF9151 modem FW files

Downloadable from
https://www.nordicsemi.com/Products/Development-hardware/nRF9151-SMA-DK/Download?lang=en#infotabs
there is currently a modem firmware file named
"mfw_nrf9151-ntn_1.0.0-1.alpha.zip" and more like that will probably
come. So the app should not warn that this is an invalid file name.
