Is it possible to add a class to the picture element that is created via the Astro Picture component?
``` <Picture
src={TestimonialImg1}
formats={["avif", "webp"]}
fallbackFormat="jpg"
alt=""
layout="constrained"
widths={[320, 480, 640, 800]}
priority={false}
class="testimonial__picture"
/>```
My class is on the img itself, and if I do width: 100% and height:100% it doesnt do anything because the picutre is the container and I cant style it
