[Bug]: Visual styling issues with AILabel, revet and error states in form fields

[alisonjoseph]

There are various visual bugs when combining props for the form components below. We need to be sure to look at all variations of the following props. The updated decorator prop adds a wrapping div that wasn't present with the slug prop so can cause some styling differences.

• slug
  • with AILabel
  • with AILabel with revert set to true
• decorator
  • with AILabel
  • with AILabel with revert set to true
• warn
• invalid

Components

• NumberInput - spacing off for error icon with AILabel & with revert true
• FluidNumberInput - Extra divider
• TextArea - Error/Warn icon overlaps AI Revert
• MultiSelect- missing divider with error + decorator
• FilterableMultiSelect - missing divider with error + decorator
• ComboBox- missing divider with error + decorator
• Dropdown- missing divider with error + decorator
