Backport PIM relevant changes

[Carl Schwan]

Hi,

It would be great if distros could backport the following two patches merged today:

- https://invent.kde.org/frameworks/kirigami/-/merge_requests/1837 to fix the menubar of Merkuro

- https://invent.kde.org/pim/kdepim-runtime/-/merge_requests/245 to fix a immediate crash of the IMAP resource on start when using something else when using the secret service of QtKeychain.

Thanks,
Carl
