Upgrade nx

[georg-schwarz]

Upgraded NX to latest version and fixed emerging issues

• NX migration via nx migrate latest and nx migrate --run-migrations. I didn't check in the migrations.json file
• Linter seems to have slightly changed, so I fixed it all required places
• Fixed webpack configurations (missing config file not added by migration)
• Remove conflicting linter rules from monaco-editor. The optimal way would be to remove the conflict, but we don't write much react anyway, so I'd just remove the jvalue eslint as a workaround...

Open Issues

• the docusaurus plugin for nx is outdated and still references old @nrwl packages - not fixable right now

There are some comments I'd rather still have included.

NX supports reading JSON files with comments but they get stripped when updating (See nrwl/nx#4244 (comment))

There is also a workaround, I'm not sure if I like it though :D
