UnicodeData.java has no regeneration task [LUCENE-9901] #10940
Description
When moving build system to gradle, we lost the following groovy script, which is used to regenerate the UnicodeData.java file to be in line with the actually used ICU4J version. The groovy script is still in the repository, but it's no longer used by the build system:
https://github.com/apache/lucene/blob/d5d6dc079395c47cd6d12dcce3bcfdd2c7d9dc63/lucene/analysis/common/src/tools/groovy/generate-unicode-data.groovy
To execute it, we need to convert it to a Gradle task that depends on the same version of ICU4J that we use as analysis/icu dependency Not sure how to do this, maybe it's easy using palantir).
The file should also be hashed and put into the regenerated file hases:

Old Ant task is here:
