Create a new translation file by running

just add-translation <locale>  # just add-translation fr_FR

New <locale>.ts file appears in the i18n directory

Translate the ts file using Qt Linguist 6:

pyside6-linguist i18n/<locale>.ts # pyside6-linguist i18n/fr_FR.ts

To test the translation:
- Make the application portable
```
touch portable
```
- Run
```
just build-develop
```
- Start the application and close it
- Edit the appdata/settings.ini
```
[Common]
language=<locale>
```
- Start the application
