KaiOS could be mistaken for iOS

[varoot]

Overview

When ua-parser-js returns KaiOS, browser.isIOS is true instead of false.

This is because we use .includes instead of equal on this line in browser.ts

Example of user agents that would result in the bug

• Mozilla/5.0 (Mobile; rv:37.0; 4044V) Gecko/68.0 Firefox/101.0 KaiOS/1.0
• Mozilla/5.0 (Mobile; Nokia_8110_4G; rv:48.0) Gecko/48.0 Firefox/48.0 KAIOS/2.5

Example failing test:

  it('does not confuse KaiOS with iOS', () => {
    const browser = new Browser({
      userAgent:
        'Mozilla/5.0 (Mobile; rv:37.0; 4044V) Gecko/68.0 Firefox/101.0 KaiOS/1.0',
    });
    expect(browser.os).toBe('KaiOS');
    expect(browser.isIOS).toBe(false); // currently this fails
  });

Note: It looks like the newer versions of KaiOS might have been flagged as Android instead, so not sure how much impact of this bug would be.
