chore: Removal of InputIconContainer (#2838)

Fixes: #2501  

Removed `InputIconContainer` because it doesn't handle bidirectionality or icons at the start of an input. Please use [`InputGroup`](https://workday.github.io/canvas-kit/?path=/docs/components-inputs-text-input--icons) from Main.

[category:Components]

Release Note:
We've removed `InputIconContainer` from Main. Please use [`InputGroup`](https://workday.github.io/canvas-kit/?path=/docs/components-inputs-text-input--icons) from Main instead.
