Update CHANGELOG.md

As of the last two pull requests were merged in the main branch, I think they will enter the next 1.1.5 version. So the CHANGELOG file needs to be updated to describe the latest changes.

- [Add approve method to Payments resource](woovibr#61)
- [Add Accounts Resource to PHP-SDK](woovibr#62)
