Update generated CSS and JS files

[sebastian-meyer]

• Add dependency grunt-cli to Build/package.json
• Update dependencies in Build/package-lock.json
• Use node.js 20.x for grunt workflow
• Update generated CSS and JS files (running grunt less & grunt terser)

This completes PR #230.

@gnuj I did the npm update magic, but the GruntComparison build still fails. Do you have an idea what could be wrong here? Is it maybe the old Node.js version (12)?

[stweil]

Grunt 1.6.1 (in your package-lock.json) requires Node.js 14 or later.

It seems to work with Node.js 18, but then creates a different Resources/Public/Css/allStyles.css.map (see https://github.com/slub/dfg-viewer/actions/runs/10044988488/job/27761266962?pr=293).

Finally! Thank you for your assistance, @stweil!

GitHub doesn't allow reviewing my own PRs and also doesn't allow me to merge this without a review. Could you please have a look at this when you are back in office, @beatrycze-volk?

[gnuj]

Good work! 👍 I also dug a little deeper yesterday and found one or two other NPM issues, which also would be solved by raising the node.js version. So no additions from my side.

@stweil and @sebastian-meyer thank you for solving this problem :)
