[Bug]: Legends for Donut chart do not honor case - automatically converts to Pascal case

[kamancha1]

Charting Control

DonutChart

Package version

5.13.9

React version

17.0.2

Environment

System:
    OS: Windows 11 10.0.26100
    CPU: (8) x64 11th Gen Intel(R) Core(TM) i7-1185G7 @ 3.00GHz
    Memory: 7.29 GB / 31.71 GB
  Browsers:
    Chrome: 131.0.6778.86
    Edge: Chromium (130.0.2849.56)
    Internet Explorer: 11.0.26100.1882

Current Behavior

Currently legends Text is automatically converted to pascal case - where each word in the legend starts with capital case.
Even if we are passing it lower case -
Eg: "Value abc" is automatically converted to "Value Abc"

This is counter-intuitive and breaks consistency with our other views.

Expected Behavior

Library should honor the case passed on the text, leaving it to the caller to decide required case.

Or at least have a way to opt out of this automatic capitalization

Reproduction

Steps to reproduce

1. Create a donut chart from Fluent UI React charts
