Update Vue, Codex and related dependencies (#833)

Needed to use --legacy-peer-deps here as npm seemingly
doesn't allow installing/ updating a package and its
peer dependencies (@wikimedia/codex which has a peer
dependency on vue, thus they would need to be updated
in a single transaction).
This seems to be desired behaviour, per:
npm/cli#7719 (comment)

npm install --legacy-peer-deps vue@3.5.13 vue-tsc@2.2.0 \
vuex@4.1.0 @wikimedia/codex@1.20.0 @wikimedia/codex-design-tokens@1.20.0 \
@vue/server-renderer@3.5.13
