Update requests for packages built by Manjaro developers

[cscs]

Plasma packages related slimbook are in a similar state.

Example here:

Dependency error on latest update

Ah, had not realized there were even more packages involved. This should probably be brought to the attention of packager people @Yochanan @philm I really do not know whats contained in that package. But I might guess its also not compatible with plasma6. For now you will either need to wait, or bite the bullet and remove them.

Its beginning to look like a lot of these OEM/partnership packages are specifically being missed.
Which is probably not very desirable.
