Fix custom Pie animation bug (#4528)

## Description

This PR is for the issue with `PieChart` that custom animations do not
work when `isAnimationActive` is set to true

## Related Issue

[Enable CSS transition for sectors on hover in PieChart with
isAnimationActive as
true](#4216)

## Motivation and Context

After digging into the code, I found that the `key` in the `Animate`
component causes the problem. The dynamic key triggers the process of
remounting the component, which overrides the custom animation. It also
adds rendering burden: if a user sets the mouse hover animation, every
time the user hovers over one piece of the pie chart, the entire pie
chart will re-render.

## How Has This Been Tested?
