docs: 24.04.4 mixup with 24.04.3

[vosdev]

24.04.4 was added but incorrectly. 24.04.3 is now missing and the Release Notes and Date next to 24.04.4 belong to 24.04.3

Can I work on this issue, please? @rkratky

[rkratky]

Go ahead! :-)

@rkratky Should I wait for PR #427 to be closed, before opening a new PR concerning the same file? Or what is the best approach here?

[rkratky]

Probably. We're just waiting for an approval there.
