Danish not recognized

[LuigiImVector]

I was trying to use fpb.json to improve my telegram bot (EbookFoundation/free-programming-books#6263) and I noticed an anomaly, there is an element with no language:

{
  "language": {},
  "index": {},
  "sections": [
    {
       "section": "C",
       "entries": [
          {
             "url": "https://web.archive.org/web/20190701062226/http://artcreationforever.com/bgnet.html",
             "title": "Beej's Guide til Netvarksprogrammierung",

The problem is that on free-programming-books this file is called free-programming-books-dk but on the languages.js the Danish is equal to da.

I didn't create a PR to rename the file because I don't know which language code to use; ISO 639-2 list says that the code of Danish language is da.

Using the search the resources are there, although with some resources writing the full title does not find them, you have to delete a few characters, for example:

• Object-oriented Programming in C#: you have to delete in C#
• Objektorienteret programmering i Java: you have to delete ava

Obviously without language.code value the result is:

Danish full ICU locale code is da-dk

da: language
dk: country

https://www.localeplanet.com/icu/da-DK/index.html

so should be renamed in fpb

let's wait for a response from @brogan20

As far as I can tell the file in fpb should be da as it is recognized as such in the site David listed here and also in the resource listed by ImVector. da-DK is the language code for Danish specifically in Denmark. The problem could be temporarily fixed in fpb-search by changing the code in languages.json to dk until the filename in fpb is changed
