Achieving translations coinstallability for KF6

[Luigi Toscano]

(I had this ready from yesterday and then I've seen Harald's email which
touches the topic, so it's time to go)

Hi,

the extraction of translations for the Qt6-based branches has been stable for
a few days now.

Now it's probably time to to address the co-installability of KF5 and KF6
translations, which means replacing 5 with 6 in the names of the translation
catalogs.

I would like for this renaming to happen in a coordinate way, so that we
(transalation coordinators) can rename the existing translation files at the
right time after the renaming, and without having to process just (say) one
translation catalog a day and drag this task forever.

My idea is to send batches of merge requests which, for a certain repository,
change a translation catalog, both its usage and its generation. When a
certain amount of MRs passes the pipeline, merge them and work on renaming the
catalogs at the same time.
The amount of rename MR opened at the same time is most likely going to be
linked to the time slot I can allocate from time to time.
Should you need to expedite the renaming of a specific translation catalog,
that would still be possible with a bit of coordination, as it usually
happened so far with catalog renaming.

Do you think it could be acceptable, or do you have want to move differently?

Ciao
