Update language.json

[nskybytskyi]

As of 6/9/22, Codeforces added new programming languages. Harwest will break if a user has submissions in these new languages. This issue has been reported in #23 . Since then, #24 and #25 attempted to fix it. However, #24 does it incorrectly by breaking code structure, and #25 only adds one new Kotlin version out of 9 (nine!) languages added.

Summary of changes:

• added new languages;
• sorted keys alphabetically—simpler change detection. It is much easier to add new languages to a sorted list. In particular, it gives an easy way to visually check for duplicates.

Closes #23 closes #24 closes #25

In case you are curious about how I found the new languages: I submitted a Compilation Error solution in every language and checked /api/user.status to obtain Submission.programmingLanguage as used in the API. Unfortunately, it often differs from the language name shown by the /submit page itself.
