fix(@vtmn/react): support style prop for `VtmnDropdown` component

[lauthieb]

Changes description

Closes #1400 (thanks @jdeca-decat for reporting this)

Context

For your information and to avoid breaking changes for people that already uses VtmnDropdown, I didn't spread all the props object. I preferred to only pass through the style prop.
