feat(editor): Update `element-plus` to 2.4.3 (no-changelog)

[MiloradFilipovic]

Summary

This PR updates element-plus dependency to 2.4.3 so we can use the append-to attribute in Dialog component. This will be needed in order to implement new n8n grid layout where modals can appear in the content area or in body (compared to current setup where they are teleported to body by default).

There have been side side-effects to the update, so please take a look if all makes sense when reviewing:

1. Looks like there is a clash with vueUse version which made v-on-click-outside directive to stop working (but only in production builds). I removed it and switched to using it as a function or component.
2. New version of element-plus is using aria attributes differently so had to update design system snapshots accordingly
3. It also started using the aria-controls attribute which is dynamic id generated on each build and that broke some of the snapshot tests. I couldn't figure out better way so added a script that removes them from snapshots before running tests
4. Some e2e and unit tests were updated to work with new html

Please take a look if that makes sense and feel free to suggest a better approach here 🙏

Latest e2e tests run
