Electron 12 deprecated `electron.remote` and the functionality was removed in Electron 14, but became available as a separate `@electron/remote` module. This commit makes the transition to the external module as an intermediary step to enable updating to a newer Electron version.
Change-type: patch
- use `import * as i18next from 'i18next';` instead of `import i18next from 'i18next';` and add an specific env to bypass mocha test
- optimized several translations
