Tweak the design of the Toggle component

[connor-baer]

Purpose

The Toggle's shadow is using a "hard" style for shadows which we don't have anywhere else. This has become especially noticeable with the new color tokens.

Approach and changes

• Replace the Toggle's hard shadow with a soft one
• Fix some of the disabled colors

Definition of done

• Development completed
• Reviewers assigned
• Unit and integration tests
• Meets minimum browser support
• Meets accessibility requirements
