Fix typespec for Cldr.with_locale: Allow strings for locale argument

[nTraum]

Cldr.with_locale allows passing strings for the locale, as already verified by one of the tests in test/cldr_test.exs:319

assert Cldr.with_locale("fr", TestBackend.Cldr, fn -> Cldr.get_locale(TestBackend.Cldr) end) == fr_locale

Thanks very much raising the issue and for the PR. I ended up manually updating the code since the right typing for the flexible locale parameter is Cldr.Locale.locale_refernce(). And I needed to apply the same changes to the backend module. I also added a a module to exercise Cldr.with_locale/2,3 so that type bugs get surfaced earlier.

The result is ex_cldr version 2.37.3 with the following changelog entry:

Bug Fixes

• Fix spec for Cldr.with_locale/3 and MyApp.Cldr.with_locale/2. Thanks to @nTraum for the PR. Closes #215.

Enhancements

• Adds <backend>.put_gettext_locale/1.
