[Enhancement]: infer_dtype_bydata can not infer DataType.ARRAY

[zc277584121]

Is there an existing issue for this?

• I have searched the existing issues

What would you like to be added?

I have tried some examples, and infer_dtype_bydata can not infer DataType.ARRAY from any type of array-like data. Maybe pymilvus should offer a function to infer a ARRAY datatype, as well as the element type within the array.

Why is this needed?

Because someone want to use this function to infer ARRAY type from metadata in Langchain.

In the past, we can use infer_dtype_bydata to infer any types such as FLOAT_VECTOR. However, this failed when infering ARRAY data

Anything else?

For int array also it will return datatype as FLOAT_VECTOR, for float array also same issue
