Disable the @typescript-eslint/dot-notation rule in favor of the noPropertyAccessFromIndexSignature TypeScript option

[leroykorterink]

The noPropertyAccessFromIndexSignature TypeScript option conflicts with @typescript-eslint/dot-notation. TypeScript options should take precedence, this means that we should disable the @typescript-eslint/dot-notation rule.

Not sure if I like the TS rule though :(

The rule itself does make sense (https://www.typescriptlang.org/tsconfig#noPropertyAccessFromIndexSignature) in that it reflects the type system properly, but it doesn't align with how we want to write JS in most cases (using ['key] syntax only when using dynamic keys from variables).
