Use php.ini-development by default instead of production one

[Slamdunk]

Hi, currently this GA installs PHP with its default php.ini, which is for Linux the one taken from Ondrej repositories (https://deb.sury.org/) as far as I can tell.

Those packages install PHP selecting the php.ini-production config from php-src, which sets for example error_reporting to E_ALL & ~E_DEPRECATED & ~E_STRICT instead of E_ALL.

But as a Continuous Integration services, it would be preferable to have the php.ini-development one.

I in fact noticed this because a test of mine was failing locally but not on GA, which rang a huge bell into my mind.

Here's the full diff for PHP 8.0 between the two. You can see that all the differences are worthy for a CI environment:

I would not like to change it right now. May be in next major version this can be done.
Currently, I think the ini-values input can be used as per the project requirements.
