Screenshots/Recordings/Graphs

These images are slightly modified from the ones that @nameisCruzCruz provided in #5932. (The previous images look like this as I had to use screenshots from PrusaSlicer)

Thanks @cochcoder
Since Curz and his team has been printing and testing these machines extensively, I'm thinking it probably make sense to use the parameters he provide(Cruz is from RatRig team).
Please let me know if you have any concerns.

If you are fine with it, I will upload this V4 profiles

I am currently going through the profiles and finding what differences have been made and implementing them into the current profiles so that custom profiles shouldn't be broken.

I'll make this PR as a draft as its probably best to include all the changes in one PR.
