Changelog top level date is wrong

[Vrixyz]

Looking at the changelog is confusing due to 2022 being listed on the top level, it should probably be "unreleased". But then we see "unreleased" later.

Lines 1 to 23 in cb2352f

Unsure why 5.0.0 has a date. Its not released but we have to be careful how we mark it because we have regexes that will match on certain text to update the changelog on release.
