chore: fix ESLint and TypeScript issues

[Dschungelabenteuer]

What Changed

• Removed plugin:node/recommended from .eslintrc.js because it caused ESLint to raise a lot of node/no-unsupported-features/es-syntax errors in TypeScript files. I'm not sure why it was actually used, please let me know!
• Explicitly set ESLint parser to @typescript-eslint/parser so that it actually processes TypeScript files.
• Added @typescript-eslint devDependencies for better compatibility between ESLint and TypeScript (it disables conflicted rules e.g. no-unused-args when actually defining a type, etc.)
• Refined a bit some typing for the no-uninstalled-addons rule so that is is slightly more precise
• Ran the autofix in the whole project and manually fixed remaining warnings/errors
• Made sure to provide adequate fallbacks when using optional chaining after the above changes
• Unused types inside lib/types/index.ts (RecommendedConfig, the generic TOptions is on StorybookRuleMetaDocs which itself doesn't seem to be used anywhere) got removed.

What did not change

• There is a whole block with an attached TODO note which raises ESLint problems: I started to look into it. However, required changes look a bit less trivial, I guess it deserves a PR on its own so that it can be further discussed.
• Same thing about TypeScript and ESLint errors on the generated example rule.
