Steps:
Tests Month value by type consistency between CLDR and Java, using "JANUARY" and "SHORT" as input.
For example: on language tag pa-PK. As CLDR's definition, locale pa_PK will be replaced to pa_Arab_PK in supplementalMetadata.xml file. There is no element of monthContext [@type=format]/monthWidth[@type=abbreviated]/month[@type=1] in pa_Arab_PK.xml file, but as CLDR fallback mechanism, should fall back to pa_Arab.xml file, but still there isn't abbreviated month in pa_Arab.xml, and then fallback to root.xml as CLDR defined, then should return "wide" type instead "abbreviated", so the result should be جنوری

The issue happens on locale pa-PK, sr-ME, uz-AF. The reason looks like Java doesn't handle languageAlias.

To compare the output format in Java, by running below code.
public void getMonthElement() {
        String tag= "pa-PK";

        Locale target = Locale.forLanguageTag(tag);

        Month day = Month.valueOf("JANUARY");
        TextStyle style = TextStyle.valueOf("SHORT");
        String actualResult = day.getDisplayName(style, target);
        System.out.println(actualResult);
    }

Result:
The output of Java is "ਜਨ", instead of جنوری.
