remove ConcatSpaceFixer

remove ConcatSpaceFixer in whatwedo-symfony.php

$ecsConfig->ruleWithConfiguration(ConcatSpaceFixer::class, [
        'spacing' => 'none',
    ])

symfony standards do not use spacing after . https://symfony.com/doc/current/contributing/code/standards.html#structure

The PER-CS2.0 ruleset of Symfony doesn't match the documentation.

https://symfony.com/doc/current/contributing/code/standards.html#structure

Add a single space around binary operators (==, &&, ...), with the exception of the concatenation (.) operator;

https://cs.symfony.com/doc/ruleSets/PER-CS2.0.html

concat_space with config: ['spacing' => 'one']

I prefer a space around the dot, which makes things more readable.
What's your take @rugbymauri @tuxes3 @xarem

@marcwieland95 i did not know that both ways are documented. In that case we can use the more used PER-CS2.0 style. starting from whatwedo/PhpCodingStandard@^v2.0

I added it accordingly into the v2.0.0 release
