Fix - Sandpack error icon overlapping issue (#4332)

* position error icon correctly

Add padding right to line with the error to accommodate space for the error icon.
Added in a new selector because it was getting overridden by more specific selectors.
Fixes #4287

* use important instead of selectors

* fix overlapping for smaller screens

* replace width with min-width

* align error icon to center vertically

Use em instead of pixels for padding, increase line height of error icon
