Portable copy safe creation fixups (#16850)
Fixup of #16686
Fixes #16847
Summary of the issue:
When updating a portable copy either from the auto-update check UX, or through the portable copy CLI, a warning is shown to confirm if a user wants to update and overwrite the portable copy.
This is not ideal UX, as the update check UX should assume the user wants to update, same with the portable copy CLI.
Additionally, some translator strings in #16686 were not formatted correctly
Description of user facing changes
Warnings are no longer shown when updating a portable copy via the auto-update UX or via CLI.
Warnings are still shown when overwriting any other directory via CLI.
Messages in warning dialogs are now translatable correctly
Description of development approach
Fix format of translation strings
check if an update is being performed when creating a portable copy via CLI, do not warn in that case.
The portable copy auto-update UX uses the CLI to perform the update.
