Mnemonics in headerbar menus conflicts with keyboard shortcuts

[Michaël Berteaux <michael berteaux live be>]

Hello translators !


There is the following bug in Evince:
https://gitlab.gnome.org/GNOME/evince/-/issues/1562

Mnemonics in headerbar menus do not work if they have a letter in
common with keyboard shortcuts. As you will see in the issue, this is a
bug fixed in GTK4, but not in GTK3.

Could you check your respective translation to adapt it? (maybe it's
worth it for translations of other software).

Thank you!
