Add ordinalization for locales with simple pattern

[c960657]

According to CLDR, a lot of locales use the same ordinalisation pattern for all numbers:
https://github.com/unicode-org/cldr/blob/12380e8/common/supplemental/ordinals.xml#L16-L18

Of these locales, the majority inherit from the simple rules defined in root.xml:
https://github.com/unicode-org/cldr/blob/12380e8/common/rbnf/root.xml#L698-L703

The rule just says that a number is ordinalised by adding a trailing period (aka ordinal dot), just like we currently do for German:
https://github.com/svenfuchs/rails-i18n/blob/master/rails/ordinals/de.rb

In fact, the rules for German are so simple, so we don't have to use Ruby files but can just use YAML files like in rails/locales/. Also, there was a bug in the existing definitions for de-AT, de-CH and de-DE – they all define rules for de, not for each region-specific locale.

Based on the tool from #1107 I used Cldr::Export.export(components: [Rbnf], …) to generate rbnf.yml for all rails-i18n locales whose CLDR counterpart includes an rbnf.xml. In order to get proper inheritance from root, I applied this patch: ruby-i18n/ruby-cldr#257.

I then found all rails-i18n locales whose ordinal rules were identical to the rules defined in root.xml. For each of these locales I generated an identical file in rails/ordinals.

Good find! 👏🏻

Can you please add en-CA to this list as well?

[c960657]

@pouyaemami But en-CA doesn't have a “simple” pattern (as defined in this PR), does it?

Ah, I think I missed the point of this PR. You're right, this isn't what I was hoping for. My issue is that I get this error: Translation missing: en-CA.number.nth.ordinalized but en-CA and en have the same ordinalized values and I assumed that this PR takes a known ordinalized value from a base locale and applies it to the region specific one.
