[I] [C++][Parquet] Wrong variant extension name [arrow]

HuaHuaY opened a new issue, #49081:
URL: https://github.com/apache/arrow/issues/49081

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   The extension name of variant is set to `parquet.variant` but arrow's specification requires  `arrow.parquet.variant`. https://arrow.apache.org/docs/format/CanonicalExtensions.html#parquet-variant
   
   ```cpp
   // cpp/src/parquet/arrow/variant_internal.h:49
   
   class PARQUET_EXPORT VariantExtensionType : public ::arrow::ExtensionType {
    public:
     explicit VariantExtensionType(const std::shared_ptr<::arrow::DataType>& storage_type);
   
     std::string extension_name() const override { return "parquet.variant"; }
   
     bool ExtensionEquals(const ::arrow::ExtensionType& other) const override;
   ```
   
   ### Component(s)
