Rule proposal: no-useless-object-entries-lookup

[fisker]

Description

I found this pattern

eslint-plugin-unicorn/rules/no-unnecessary-polyfills.js

Lines 130 to 132 in e48a620

	const [, features] = Object.entries(coreJsEntries).find(
	entry => entry[0] === `core-js/full/${namespace}${method && '/'}${method}`,
	);

in #2582, which use Object.entry to search for a specific key and access the value, which should use a direct object property access instead.

Examples

// ❌
const [, value] = Object.entries(object).find(([key,]) => key === 'something');
const value = Object.entries(object).find(([key,]) => key === 'something')[1];
const value = Object.entries(object).find(([key,]) => key === 'something')?.[1];
const [, value] = Object.entries(object).find((entries) => entries[0] === 'something');
const value = Object.entries(object).find((entries) => entries[0] === 'something')[1];
const value = Object.entries(object).find((entries) => entries[0] === 'something')?.[1];

// ✅
const value = object.something;

Proposed rule name

no-useless-object-entries-lookup

Additional Info

Note 1: this rule should ensure the searching key can't be object builtin properties/methods.

Should ignore this case, since foo can be constructor or something else which is in object prototype.

Object.entry(object).find(([key]) => key === foo)

Note 2: Maybe it's also hard to detect that object is a plain object.
