Closes: #44915
Changes Made:
Updated the @Keyframes circular-rotate animation in CircularProgress.js:
Changed the stroke-dasharray value from 100px to 1px for the 100% keyframe.
Adjusted the stroke-dashoffset value to -126px for greater precision.
Before:
The animation shows an odd "jump" as the arc moves quickly and then stops suddenly between the 50% and 100% phases.
After:
The animation is smooth and symmetric, with the arc contracting back to 1px between the 50% and 100% phases.
