fix: remove type attribute from script tag

[waltjones]

Description of the change

This PR removes the type attribute from the script tag that gets inserted for the js snippet. For HTML 5 it is strongly recommended to not include this attribute, and for HTML 4 all browsers assume javascript, so the change is safe there as well. This change will help prevent static analysis warnings for some users.
