build: Enable the verbose mode for PHP-CS-Fixer

[theofidry]

Without this, when there is a diff, it does not show which rule is applied:

--  11) .php-cs-fixer.dist.php
++  11) .php-cs-fixer.dist.php (single_line_comment_spacing)
      ---------- begin diff ----------

     'no_unneeded_control_parentheses' => false,

(see the first line).

@Wirone is there any reason why this is shown in verbose mode? I struggle to see a case where you would not want that.

[Wirone]

@theofidry it was like that before I joined, so maybe @keradus can share more info. From my understanding when you want --diff, you do not necessarily want to know the reason for the diff, but only the final result, hence the --verbose as an additional flag for even more details. But yeah, in the past I also had some doubts about it 😊.

[theofidry]

Honestly even the --diff during --dry-run is dubious to me.

It seems much more common and the expected behaviour when first using the too to:

• know what is causing the change
• what the change is

Caring only about whether there is a change without the cause or what the change is, is a much more narrow use case IMO for which a --quiet flag would do just fine.
