feat: Rename reset mixins to include element name

[RubenSibon]

Describe the pull request

What

Rename Sass reset mixins to include the HTML or common name of the element they reset.

Why

This refactor is not really necessary, but makes it somewhat easier to understand what each reset mixin does. It also helps with global searches on the word "reset".

How

Global search on @mixin reset and then changing those names by inluding the element name after a dash.

Checklist

• Start the PR title with a Conventional Commit prefix, as explained here.

Additional notes

• There are some instances where an HTML name was not used: paragraph instead of p, list instead of ol or ul and heading instead of h1 to h6. Please check if this makes sense.
• One reset applies to both a dd and a label element. In this case the reset is named reset-label-or-description.
