[TASK] Cleanup eslint configuration

We renamed the eslint configuration to follow the recommended standards
so developers IDEs will pick up the configuration more easily.

The ruleset was adapted to follow a wider range of recommendations.
- eslint:recommended
- @typescript-eslint/recommended
- lit/recommended
- wc/recommended

In addition we now also force more kinds of spacing rules to avoid
IDEs having different opinions on how to format for example includes.

The only recommendation we don't want to follow is
- @typescript-eslint/no-inferrable-types.

spotting mistakes more easy when writing code.

Rules that are currently in "warn" mode:
- @typescript-eslint/ban-types
- @typescript-eslint/no-explicit-any
- @typescript-eslint/no-this-alias

To only check for errors run in the Build directory:
- npx eslint ./Sources/TypeScr...
