CHANGELOG.rst have wrong year for latest update

I believe it should have 2023 year

https://github.com/pytest-dev/pytest-subtests/blob/85cb300c915b4da50612f3df72551c44d43cd620/CHANGELOG.rst?plain=1#L4

I'm not sure if changelog is auto-generated using some tooling or done by hand, so filing an issue rather then opening PR with manual year fix, hope it's fine.
