Fix(PR template): enhance readability, go straight to the point

[Marc-Andrieu]

Description

Summary

• The other day I created a Hyperion PR and I was lost in the template: I was drowned in too much text by default.
• Also, some ppl definitely didn't read the instructions, also drowned in text.
• Thirdly, there was a spacing bug in the classification that rendered it way to spaced between checkboxes

Changes Made

Here I'm using the enhanced PR template, so you can have a feel of what it looks like (both in code and rendered)
