Describe the bug commit: c7afc3bee93563af3c7073adfdd5cbd9b584ca0e Get 520 when requesting zh-Hant-alt-long language's display name with API /i18n/api/v2/locale/supportedLanguageList.

To Reproduce Steps to reproduce the behavior:

1. Put a json file with name: messages_zh-Hant-alt-long.json in VMwareVIPLocale&1.0.0 bundles.
2. Request its displayname with "http://serviceip:8091/i18n/api/v2/locale/supportedLanguageList?displayLanguage=en&productName=VMwareVIPLocale&version=1.0.0"

The issue happens when there is below kind name(region is named with low case) of file: pt-pt, fr-fr ... Other languages can't be shown due to the issue, and locale should not be case sensitive, set the priority to high.

No 'zh-Hans-alt-long' language in cldr-32.0.0 version, it should be new added data in cldr master branch, but this kind of issue has been fixed, you can verify the fix with 'en-US-alt-short'.

@huihuiw01 the kinds of 'en-US-alt-short' and 'pt-pt' are fixed with commit 764529a5503cf3183c300c0e86ade72bc8eb3f2c. But below data is returned for this kind 'zh-alt-long' language:

{
        "languageTag": "alt-Long",
        "displayName": "Southern Altai ()",
        "displayName_sentenceBeginning": "Southern Altai ()",
        "displayName_uiListOrMenu": "Southern Altai ()",
        "displayName_standalone": "Southern Altai ()"
      }

For locale "zh-alt-long", its display name can be shown correctly with commit e768e131422a9494f1d04a82a4f33a7d65a6981c:

Communicated with dev @huihuiw01 , for the locales aren't supported in languages.json file, should use the combination of language+script+territory+variant for its display name. locale: zh-Hant-alt-stand-alone should be: Chinese(Simplified Han) In languages file: "zh": "Chinese" In scripts file: "Hans-alt-stand-alone": "Simplified Han", locale: cs-CZ-alt-variant should be: Czech(Czech Republic) In languages file: "cs": "Czech", In territories file: "CZ-alt-variant": "Czech Republic",
