Robert Muir resolved LUCENE-10239.
----------------------------------
    Resolution: Fixed

I've opened LUCENE-10243 to bump the unicode versions of the grammars. Will split out an issue to use the new features to simplify grammars and gradle build as well.

> When reviewing LUCENE-10238, I noticed we still had unicode 9.0 data specified for our jflex tokenizers. 
> According to the changelog I see some key benefits from upgrading to jflex 1.8.2:
> * unicode 9 -> unicode 12.1
> * remove our custom emoji regeneration via ICU, as jflex supports emoji properties directly now.
> * Less RAM at runtime to users (two stage tables): https://github.com/jflex-de/jflex/pull/697
