## What is the current behavior?

`ion-primitives-neutral-500
- Changes the toggle background color for pressed states:
`ion-bg-primary-base-press` and `ion-bg-neutral-base-press`, for checked
and unchecked toggles, respectively
- updates the toggle snapshots accordingly

## Does this introduce a breaking change?
