Correct the units and tooltip in "Private storage max size"

[emanruse]

The problem you're addressing (if any)

The tooltip for "Private storage max size" in qube Settings GUI seems a useless explanation of the wrong choice of units.

The solution you'd like

Instead of the tooltip for "Private storage max size", explaining the "binary definition of megabyte and gigabyte", simply use the proper units - mebibyte (MiB) or gebibyte (GiB).

Also make that consistent with the units for memory in Advanced tab.

The value to a user, and who that user might be

A clear, straightforward and correct unit, instead of explanations for a wrong one.

PR Submitted.

Minor fix mostly for cosmetic purposes.
Review priority: Low

p.s.: The fix for memory units (and others) will come for #7889

The qvm-prefs manual still reports memory unit as MB (Megabyte) and not MiB (Mebibyte). Should this issue be reopened or a new one created?

I submitted the required fix (also for qvm-ls code comment). A minor change.

The fix was merged, this can be safely closed again :)
