Fix $page->waitForLoadState() handling

[stloyd]

Kinda reproducer:

$page = Playwright::firefox(['headless' => true])->newPage();
$page->goto('https://example.com');
$page->locator('input[name="password"]')->fill('password');
$page->locator('button[type="submit"]')->click();

$page->goForward();
$page->waitForLoadState();

This fixes errors like:

Fatal error: Uncaught Playwright\Exception\PlaywrightException: Unknown action: waitForLoadState in /project/vendor/playwright-php/playwright/src/Page/Page.php:626
Stack trace:
#0 /project/vendor/playwright-php/playwright/src/Page/Page.php(846): Playwright\Page\Page->sendCommand('waitForLoadStat...', Array)

#2 {main}

Hi @stloyd, thank you very much for this PR!

Could you maybe add a small test to prevent future regression?
