feat(protocol-designer): update Magnetic Module step form

[syao1226]

re AUTH-812

Overview

Updating the Magnetic module step form for single module to match the design

Test Plan and Hands on Testing

• Create an OT-2 protocol and add a magnetic module GEN1 or GEN2
• Go to the Protocol Steps tab and add a step for Magnet
• Text display for the min and max engage height for magnetic module GEN1 and GEN2 (only show unit when it's a GEN2)
• Add labware to the Magnetic Module, and there might be a recommended engage height depending on the labware

Changelog

• Added an optional caption prop to ToggleExpandStepFormField for displaying the min, max, and recommended engage height text under the input field
• Added onToggleUpdateValue() to ToggleExpandStepFormField to handle both boolean and string values, toggling between 'engage' and 'disengage' action types
• Updated Toolbox.tsx and other step forms to add or remove the borderBottom grey line
• Added test

maybe you can use Divider.

MagnetTools is https://www.figma.com/design/WbkiUyU8VhtKz0JSuIFA45/Feature%3A-Protocol-Designer-Phase-1?node-id=10435-669248&m=dev, isn't it?

If so, the copies are slightly different.
I think if you can issue a ticket that has info about what things we need to update, you can merge this PR into edge when solving CI checks.

do you mean something like updating the step name from 'Magnet' to 'Magnetic'?

@ncdiehl11 any suggestion?
