SearchInput - examples should use unique aria-labeling

[thatblindgeye]

Describe the enhancement or change
Since a11y docs will likely mention using unique aria-labels on inputs/utility buttons if there's more than 1 SearchInput on a page, we should update examples to have unique labeling.

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?
