fix(69): removing check for alt attr before printing it

[mndonx]

This PR fixes/implements the following bugs/features

• Images are currently printing no alt attribute when they should be printing empty alt attributes.

"If there is no alt attribute on the element, the screen reader will announce the name of the image file, which may not make any sense to the user." So for images that don't have any alt attribute, the preference is the image information not be read at all. Images that are NOT decorative should have alt text.

How to review this pull request

• [x] Include an image.twig embed in another component's twig template.
• [x] In the component's yml file, set the alt attribute to empty quotation marks.
• [x] Verify that the image's alt attribute is printing, but empty.
