Update Cambodia holidays: add Peace Day in Cambodia
<!--
  Thanks for contributing to holidays!
-->

## Proposed change

<!--
  Describe the big picture of your changes.
  Don't forget to link your PR to an existing issue if any.
-->

- Add ["Peace Day in Cambodia" (ទិវា​សន្តិភាព​នៅ​កម្ពុជា​)](https://admin.taftac-cambodia.org/public/pdf_file/regulation_1704245695_Z7IALJjE.pdf) for Cambodia from 2024 onwards, English translation is based from the unofficial translation in the link above and https://www.acledabank.com.kh/kh/eng/md_publicholiday . (Simply referring to "Peace Day" alone could be confusing as Cambodia already has another ex-holiday called "Paris Peace Agreement's Day")
- More test case refractors as previously recommended in #2081 .

PPsyrius: I'm thinking of adding some kind of hidden char remover to the pre-commit later to prevent that from being included in the first place again. 👀
