Support for many pluralization category (CLDR v41) #1048
Description
Starting with CLDR v40, from 2021-10-06, more languages were given a many pluralization category. For example, see the entry for Italian in the Language Plural Rules document.
rails-i18n only has logic to return many for a few languages. For languages like Italian, rails-i18n configures them with the OneOther rule, while they should now also support many, according to the CLDR.
I would like to add many to the languages where it newly appeared in CLDR v40 and v41. What would be the best practice to do this? I have not done an exhaustive investigation through the Language Plural Rules document, so I'm not sure how much is shared between the languages. If there is significant sharing, I assume a new OneManyOther pluralization rule class would be appropriate? Otherwise, I could edit the specific rules files with each language's specific rules.
