chore: adds CHANGELOG.md

Related to #55

• Generated by convco using this command:

convco changelog --include-hidden-sections > CHANGELOG.md

https://convco.github.io/configuration/#default-configuration

• Added a .versionrc because it was generated by a fork, and we need to make sure the origin is trustification instead of fork's origin.

I would recommend to:

• Don't create a CHANGELOG.md file. That only causes merge/rebase conflicts and is a pure annoyance. Putting the generated changelog into a github release section on the other hand is quite helpful.
• Don't use "link mode", disabling that will let github automatically create links and include nice hovers in addition
• You can customize the rendered output by customizing the template: https://convco.github.io/changelog/#custom-template
