Check tools part2

[n-peugnet]

• add parallel lint to check for syntax errors
• add phpcs PSR12
• add phpstan doctrine extension (to check DQL and some doctrine magic)

To fix most of PHPCS errors you can run the following command:

composer fix

All of the commands I added are composer scripts that you can check in composer.json: https://github.com/vincent-peugnet/antilope/blob/f20b95fc97dd95dc8529a92e386aeff1ca497df4/composer.json#L98-L116 Part of #17
