Update frontend dependencies

This updates all possible updates except:

• eslint specific ones
• vue styleguidist specific ones

Problem with vue styleguidist is that it is currently not possible (for me) to install newer versions and have the dispatch of compatible versions of their sub-dependencies to be compatible with our main depencencies here.

Vuestyleguidist should be externalized over all.

The other thing are eslint specific packages. There are newer versions of eslint (8.3.0) but no compatible versions for the plugins for vue & nuxt (they still require the 7.32.0 of eslint).

Update: I also updated the eslint-vue-plugin (but not to the most current package).
