Add PHP 8.1 Dockerfile

Add Dockerfile for PHP 8.1

I also clean upped the PHP extensions list because some of them are installed by default in the PHP base image.

That's awesome! Special thank for removing redundant dependencies, it's always difficult to keep track of. 🍺

Could you just remove the PHP 7.3 image? This repo only supports the 3 latest PHP versions.

Yes of course. But please consider that PHP 8.1 isn't released and the current version is an RC. Should I remove 7.3 nevertheless?

[lorisleiva]

Yes that's fine because the 7.3 image will still exist on DockerHub for anyone that uses it. It just won't be updated anymore. ☺️

[lukasleitsch]

Alright. PHP 7.3 was removed.

Thanks! 🍺
