Add Contao example to README.md

[CMSworker]

Add example for Contao CMS. This cronjob is required for the search function to work in the Contao backend.

Thanks for the contribution! Minor suggestions. Please test them out in your environment.

Suggested change

- Adjust `php8.4` to match your DDEV project's PHP version

No need to specify php version

[rfay]

Suggested change

	* * * * * /usr/bin/php8.4 /var/www/html/vendor/bin/contao-console contao:cron
	* * * * * php contao-console contao:cron

No need to specify php version, and vendor/bin is already in the PATH

Thanks. I have done several tests with the following two variants: After each change I ran ddev restart, cleared the Contao cache in the Contao manager and checked if the backend search works (also let it run 3-5 minutes and refreshed the backend).

* * * * * php contao-console contao:cron : The backend search does not work with this short variant and the database cron table is not updated every minute.

* * * * * php /var/www/html/vendor/bin/contao-console contao:cron : This variant works in my tests.

Oh sorry, I see. It's not a script.

Thanks! Will pull when you're ready.
