Use globe-outline icon for Time zone and swap Language icon to earth-outline

[eLtMosen]

Depends on adding the earth-outline icon in asteroid-icons-ion repository https://github.com/AsteroidOS/asteroid-icons-ion/pull/12

Fixes https://github.com/AsteroidOS/asteroid-settings/issues/73

• Use globe-outline icon for Time zone since it suggests zones on a globe
• Use new earth-outline icon for Language
