Wrong usage of i18n

[Carreau]

jupyter_server/serverapp.py
2861:        info += _i18n(f"Jupyter Server {ServerApp.version} is running at:\n{self.display_url}")

jupyter_server/auth/identity.py
654:                self.log.info(_i18n(f"Wrote hashed password to {config_file}"))

At least those two usage are wrong; the f-string will be formatted before the call to internationalisation. It should be _i18n(...).format().

In general we could likely grep the codebase for i18n\([^'\")], and any non-literal string in i18n will be wrong.
