feat(rotate): add keyboard shortcuts for rotating with arrow keys (#5294)

# Description of Changes

This pull request adds keyboard shortcut support to the `RotateSettings`
component, allowing users to rotate using the left and right arrow keys.
This improves accessibility and user experience when interacting with
rotation controls.

**Enhanced keyboard interaction:**

* Added a `useEffect` hook to listen for `ArrowLeft` and `ArrowRight`
key presses, triggering the `rotateAnticlockwise` and `rotateClockwise`
methods on the `parameters` object, respectively.
