Document new Symfony assertions

[ThomasLandauer]

The new assertions introduced in https://github.com/Codeception/module-symfony/releases/tag/3.5.0 should be added to the docs.
Did you copy them one by one, or did you find a way to call them directly (i.e. future Symfony assertions will automatically work too)?
Are these the ones we're talking about? https://symfony.com/doc/current/testing.html#testing-the-response-assertions

Hi @ThomasLandauer , the vast majority of the added assertions call directly to Constraints defined in Symfony. For example:

module-symfony/src/Codeception/Module/Symfony/BrowserAssertionsTrait.php

Lines 29 to 31 in cad3c7a

	public function assertBrowserCookieValueSame(string $name, string $expectedValue, bool $raw = false, string $path = '/', ?string $domain = null, string $message = ''): void
	{
	$this->assertThatForClient(new BrowserHasCookie($name, $path, $domain), $message);

while there are others that were translated to integrate with the module's service container. For example,

module-symfony/src/Codeception/Module/Symfony/HttpClientAssertionsTrait.php

Lines 17 to 19 in cad3c7a

	public function assertHttpClientRequest(string $expectedUrl, string $expectedMethod = 'GET', string|array|null $expectedBody = null, array $expectedHeaders = [], string $httpClientId = 'http_client'): void
	{
	$httpClientCollector = $this->grabHttpClientCollector(__FUNCTION__);

While, I added comment blocks for each assertion, the code examples are pending for someone to send a PR and add them.

I have updated the https://github.com/codeception/symfony-module-tests test project in all its branches to add tests to verify that these assertions work well. so the work around having that guidance available should be simple.
