Update ESLint Dependency

[holgerd77]

Our ESlint dependency is pinned to 8.22.0 (see root package.json file). This release is from roughly a year ago (August 2022, see release page) and so this is already pretty outdated and there have been various releases in between up to v8.45.0.

So we should update here, also the associated plugin versions since there have been a lot of bug fixes along the road.

I think it is likely that linting stuff will break along the road and it might therefore be wise to take this on a bit slowly and go step-by-step here and e.g. only go up 5 or so versions (and also do the plugins separately) and then run GitHub CI and see if things still work or otherwise fix linting. Then one can likely better associate what update made things break.

Side note: there is currently a parsing error shown like below in the different .eslintrc.cjs config files in the packages folders:

This can be solved by adding '.eslintrc.cjs' to the ignorePatters in config/eslint.cjs.

Maybe this can be added on the sideline here, wouldn't want to open a dedicated PR and trigger CI just for this one-line change.
