Optional schema for Korean Hangul/Hangeul

Thanks a lot for this contribution. I will add it.
But the stopwords seem wrong to me. Stopwords aren't the right choice to remove single characters or numbers, for eample a number like "57" is not touched. These should be removed within a Char Filter, see https://solr.apache.org/guide/7_5/charfilterfactories.html

The file name "_7.0.0" doesn't match the minimum required Solr version 7.5.0.

And we should add test coverage by editing https://git.drupalcode.org/project/search_api_solr/-/blob/4.x/tests/src/...

We should provide an update hook to install the config in existing sites.

Thanks @mkalkbrenner! I've created a patch based on the feedbacks.

Also, I've changed the stopwords to this list instead: https://gist.githubusercontent.com/spikeekips/40eea22ef4a89f629abd87eed5...

For the hook_update, hopefully I did it right. Kindly advise if there's other better way to do this ;)

Some parts were still missing in the patch.
