[wasm][icu] Locale aliases are not resolved correcly

[ilonatommy]

Description

"no" is an alias of "nb" locale. While "nb" is working fine with the new icudt data files from https://github.com/ilonatommy/icu/tree/dotnet/main/eng/prebuilts, "no" is throwing an exception of incorrect culture name.

Reproduction Steps

            var languageCodes = new List<string>() { "nb", "no", "nn" };
            foreach (var language in languageCodes)
            {
                try
                {
                    var culture = CultureInfo.CreateSpecificCulture(language);
                    var today = DateTime.Now.ToString("dddd, dd MMM yyyy", CultureInfo.GetCultureInfo(language));
                    Console.WriteLine($"locale: {language}; date: {today}");
                }
                catch (Exception ex)
                {
                    Console.WriteLine($"EXCEPTION: {ex}");
                }

"nn" locale, initially considered an unresolved alias, is in fact a separate locale, not listed as KNOWN_CANONICALIZED. It probably should not be added to the ICU batch.

Expected behavior

Check on Console App, it prints correctly e.g.

Actual behavior

Regression?

Known Workarounds

Use "nb" with the newest icu bundle.
