Help Casts All Input Flags To UPPERCASE In Print

When requesting help output all available flags are being cast to upper case. This makes it difficult if not impossible for users of the wrapper methods the exact case needed to call requiring opening the code to view or asking a developer for assistance which diminishes the intent of help as a self-help solution. Fire is also case sensitive when using the flags so its best that help output preserves case to avoid the mismatch.

I would prefer not to have to conform, but rather have Fire make sense in the behavior.

重現一個包含大小寫混合 flag 的命令的說明輸出，然後追蹤用於格式化可用 flag 的 CLI 說明產生路徑。完成的標準是說明輸出保留每個 flag 原始的大小寫，且顯示的拼寫仍可用於 Fire 區分大小寫的 flag 解析。
