[Axolotle]

• removal of vuex for data store
• big bump of all dependencies
• migration to typescript with full typing
• migration to new vue3 syntax called Composition API
• use of the new vue3 Suspense to allow awaitable components

PR STATUS

Beside reformating some translation (that would be better done juste before merging to avoid unnecessary conflicts on translations change), i guess it is testable. Also, bootstrap-vue-next is still in alpha but looks okish.
Ready for 12.1?

TODO:

• merge dev/bookworm
• locales
  • reformat translation (@ escapted, {c} to {n} for pluralization)
  • add missing new keys
• commit components.d.ts
• commit yarn.lock
