Show vectors with correct precision

[yhmo]

Describe the bug: Currently, Attu always shows vector data as float64. For example, a value 0.001 is displayed as 0.0010000000474974513

Steps to reproduce:

1. create a collection
2. insert some data, load the collection
3. observe the "Data" page in Attu

Attu version: 2.3.8

Attu version:

A proposal: display the value according to field type. If the vector field is FloatVector, round the decimal to 7 places. If the vector field is Float16Vector, round the decimal to 16 places. If the vector field is BFloat16Vector, round the decimal to 3 places.

I don't think attu should handle this. milvus should handle this.
