Fixed gettext usage:

- fixed gettext usage with .format() only for original text with %s
  - fixed typos
  - fixed translation yes/no buttons in the dialog.
  - improved translating sentences without "connecting" words (eg. see web/pgadmin/dashboard/static/js/dashboard.js,
     word 'cancel' needs to be translated in the Czech language as 'zrušit' but in another sentence as 'zrušení')
  - added gettext for text translations.
