Updates on this topic after the plasma BOF.

There's some concerns (by me mostly) about Plasma being committed to a
rigid schedule. As such the following was somewhat agreed upon.

We can probably delay the .12 release of KDE Gear if it's needed. The
Qt 6 transition is a special case.
If we want to delay more than 2 months, then we may as well just wait for 24.04.

At the start of September, we'll do a big online meeting with all
stakeholders and make an executive decision.
