📚 Description

This removes injections type and uses the composables functions and types where possible.

The changes to the composable JSDoc are bigger, it simplifies the descriptions and removes references to encapsulated functions (these existed because they were exposed in vue-i18n-routing). We currently describe functions in several places but it's to keep everything up to date.
