User will now get this 'warning' upon trying to install Notes from Flathub (from the command line, at least):

Info: runtime org.kde.Platform branch 6.4 is end-of-life, with reason:
   We strongly recommend moving to the latest stable version of the Plaform and SDK
Info: applications using this runtime:
   io.github.nuttyartist.notes

I understand and agree with the message, but unfortunately Qt 6.5 seems to have introduced this bug:

• [Linux] maximizing and restoring the Notes window freezes / hangs the application nuttyartist/notes#611
• https://bugreports.qt.io/browse/QTBUG-115459

So, for now, we won't upgrade to 6.5.

That being said, this release is looking great.

Merging...

Gotcha. We shall provide https://bugreports.qt.io/browse/QTBUG-115459 with a minimal reproducible example.
