fix: Fix display of select list dropdown indicator
In Bootstrap 5, <select>
lists are styled via the inclusion of the form-select
class. Among performing some common form-element styling, this allows for the "down-carat" dropdown indicator to be shown, to indicate to the user that they can interact with the element to be shown a list of options.
Prior commits neglected to add the form-select
class; this MR adds it back.
