Disable more rules covered by TypeScript in the typescript config

[FloEdelmann]

The typescript config already disables the import/named rule because it does not have an advantage over errors thrown by the TypeScript compiler:

eslint-plugin-import/config/typescript.js

Lines 31 to 32 in fa36d49

	// TypeScript compilation already ensures that named imports exist in the referenced module
	'import/named': 'off',

There are some more rules that fall in the same category, which also typescript-eslint recommends to disable:

• import/namespace
• import/default
• import/no-named-as-default-member
• import/no-unresolved (at least for import statements, but not for require calls)

To avoid checking the same things the TypeScript compiler has already checked, I think it makes sense to also disable those rules (maybe except for import/no-unresolved) in the typescript config, so users don't have to (know and) disable them manually.

(It would also mitigate #2340 for TypeScript users.)

What if the user is on an old version of TypeScript?
