 * Проверяет что переданное значение является `Number`

 * ## Пример
 *
 * ```ts
 * import assert from 'node:assert';
 * import { isNumber } from '@vkontakte/vkjs';
 *
 * assert.strictEqual(isNumber(3), true);
 * assert.strictEqual(isNumber(Infinity), true);
 * assert.strictEqual(isNumber('3'), false);
 * ```
 *
 * Для исключения `Infinity` `-Infinity` и `NaN` используйте `Number.isFinite`
 *
 * ```ts
 * import assert from 'node:assert';
 *
 * assert.strictEqual(Number.isFinite(3), true);
 * assert.strictEqual(Number.isFinite(Infinity), false);
 * assert.strictEqual(Number.isFinite('3'), false);
