https://developer.nordicsemi.com is blocking some User-Agent values on downloads

[Dan Halbert]

Our GitHub Actions CI jobs have been downloading https://developer.nordicsemi.com/.pc-tools/nrfutil/x64-linux/nrfutil for years, using wget. Very recently, this started failing. The URL still works from a browser and using curl, so it looks like wget is being blocked for some reason.

I'm assuming this is intentional (maybe to prevent AI crawlers?), but this is one consequence. Do you expect to keep this block? We'll do something else if needed.

I'm not sure why this change happened (or if it will persist), but you can download from the artifactory directly:

https://files.nordicsemi.com/artifactory/swtools/external/nrfutil/executables/x86_64-unknown-linux-gnu/nrfutil

You can get the links for other OSs by selecting on the tab and looking at Option 2 on the nRF Util documentation.

Thaniks, wget is not blocked for that URL. We might also consider keeping our own copy.
