Migrate to wamania/php-stemmer:^4.0

[alexworks64]

Hello,

please update dependency wamania/php-stemmer to version ^4.0 (from current ^3.0) for versions 2.x if possible.

That package works with PHP8.4 with deprecation warnings because of their dependency voku/portable-utf8.
In the version 4.0 they replaced voku/portable-utf8 with another package.

When I'm trying to use rubix/ml with PHP8.4, I'm getting many warnings like this because of that package:

Deprecated: voku\helper\UTF8::file_get_contents(): Implicitly marking parameter $offset as nullable is deprecated, the explicit nullable type must be used instead in ...

Thanks!

For others, the problem can be temporary fixed, seems like, with composer require "wamania/php-stemmer:4.0 as 3.0"
