Add additional tags to NIP-54 Wiki

[basantagoswami]

Language of the article

We can add language of the article this way;

{
  "tags": [
    ["l", "ISO-639"],
    ["L", "en"]
  ]
}

Or we can have some other l tag value and add the language in the form of <country code>-<language code>. For example: L with bn-BD for Bangladeshi Bengali and bn-IN for Indian Bengali

This can probably be added to the NIP-32 (Labeling) itself as an example instead of here.

Type of the article

Add a c or some tag to identify different categories of articles. Some of the categories can be:

• recipe
• tutorial (think WikiHow, but not shitty)
• definition (dictionary sites)
• chapter (something like geeksforgeeks.org, optionally accompanied by an additional tag for the course name like ["course", "How to exit vim"])

FYI, the following are PRs about the language:

• NIP-37: Language Tag #632
• relax requirements for NIP 32 L tags #1129
• NIP-XXX Internationalization and Localization #1127

I don't see why not just an l tag, or many. The L tag is useless in this case.
