Add Norwegian language to AdGuard Home

[DandelionSprout]

It's on Crowdin, so I figured I should give you guys a heads-up about it, along the lines of #1043.

I also have a bonus question: Currently the translation files on Crowdin are set to be non-exportable and non-importable. The non-exportability is a bit unfortunate for me, as I maintain something of a fully free Translation Memory for Norwegian Bokmål, and in particular I'd need to be able to use the option for "Download in XLIFF" to boost my TM with AdGuard translations easily.

Thank you!

You should be able to export it now, please check it.

I can confirm it's now exportable. Thank you once again.
