Ember Upgrade to latest LTS (Q4 2023)

[jayjayjpg]

Bug description

Description

In order to keep up with security vulnerabilities more easily, we should upgrade Ember and it's related dependencies, such as ember-cli, ember-data, as well as version-dependent addons, e.g. ember-auto-import, ember-changeset, etc. once the current LTS version that Conduit is on runs out of support.

According to the current release calendar, LTS support will run out by December 11, 2023. This means, this ticket should be picked up the latest by Q4 2023 to guarantee that vulnerabilities of the UI project can be addressed in a timely manner.
