The custom Lucene snowball stemmer is incompatible with current Snowball Stemmer [LUCENE-8195]

If someone is using [the current version of Snowball stemmer](https://github.com/snowballstem/snowball/tree/master/java/org/tartarus/snowball) as (transitive) dependency and adds Lucene Analyzers as separate dependency the libraries using the stemmers become incompatible - you either lose Lucene or the other libraries.

Here is an example of the case:

---
Migrated from [LUCENE-8195](https://issues.apache.org/jira/browse/LUCENE-8195) by Nikolay Georgiev

Start by comparing Lucene Analyzers' custom Snowball stemmer with the current Snowball stemmer sources linked in the issue, and review the dependency conflict described in the Stack Overflow example. Done means Lucene Analyzers can coexist with the current Snowball stemmer dependency without making libraries incompatible.
