Use real native Chinese names in SC index.json

[10110111]

This is a result of fetching all the constellation names from constellation_names.zh_CN.fab into index.json, yielding native names made of hieroglyphs and "pronounce" entries made of (diacriticless) pinyin.

Great PR! Please pay attention to the following items before merging:

Files matching skycultures/**:

• Did you remember to update skycultures/CMakeLists.txt file respectively to changes in sky cultures?
• Did you remember to define classification parameter in sky cultures (see index.json file)?
• Did you remember to define license parameter in sky cultures (see description.md file)?
• Did you remember to define region parameter in sky culture (see index.json file)?

This is an automatically generated QA checklist based on modified files.

Not being an expert on pinyin. Do we have diacritics in one, and non-diacritics in the other SC, or do we have unhealthy mixes now?

We have diacritics in some names of the same SC (DSO, stars) and no diacritics in others (constellations, planets). So I'd call it an unhealthy mix.

The diacritical mark is used to distinguish tones. In the Pinyin standard, as a transliterated vocabulary, it does not have diacritical marks, but as a strict phonetic notation, it has diacritical marks.
The constellation names were originally incorporated as native terms, hence their lack of diacritical marks.
In Chinese sky culture, the pinyin of star names was originally added as phonetic symbols, so there are diacritical marks.
Because at that time, constellations had native terms but no pronunciation terms, and stars did not have native terms.
Just didn't anticipate the current changes. If necessary, I can add all diacritical marks in the future.

This would be great. Yes, the project and data options have grown a lot. Ruslan and Fabien started using JSON with Stellarium-mobile years ago and added the "pronounce" key, while I had expected or preferred a "transliteration" key, while for "pronounce" I would have expected IPA annotation. There are other cases where both transliteration and pronounce and even IPA would be great. I know for Tibetan, scientists use Wylie which is not really a pronunciation help, and there is a pinyin for Tibetan as well. So, in the end we may fill tags "pronunciation" (for Chinese: "pinyin with diacritics"), transliteration (pinyin without), and "IPA" for international phonetic alphabet, if anyone can add that correctly. But these tags will not be used in 25.1 now. If you can later help filling the gaps, it would be welcome.
