Documentation: Update/fix release page changelogs to match CHANGELOG.md (plus proper changelogs for everything before 0.3.3)

Issue Checklist

• I have read the Contributing Guide
• I have checked the Issues/Discussions pages to see if my enhancement has already been suggested
• I have properly titled my enhancement

What is your suggestion, and why should it be implemented?

Title. I've always found it a little weird that 0.5.0 and 0.5.1 don't have the whole contributors for this update and new contributors this update (that, and literally every update before 0.3.3 has no proper changelog at all)!

That, and ninjamuffin99 is listed as a new contributor in one of the updates, which I find funny.

Gonna ask Eric about this.

i think they were experimenting with something that created changelogs automatically, so when it works im guessing changelogs will look right

They told us they still haven't gotten git cliff to work, so I'll be taking care of changelog polishing
