Support variadic arguments when calling addDefinitions

[juliangut]

The build error is coming from PHPStan

------ ------------------------------------------------------------------
 Line src/ContainerBuilder.php
 ------ ------------------------------------------------------------------
  314    PHPDoc tag @param for parameter $definitions with type
array<array|DI\Definition\Source\DefinitionSource|string> is not
subtype of native type array<int, mixed>

This is the code

    /**
     * Add definitions to the container.
     *
     * @param string[]|array[]|DefinitionSource[] $definitions Can be an array of definitions, the
     *                                                   name of a file containing definitions

Regarding the coding style I've added a commit on master to fix the coding style (Symfony added a new rule that breaks BC): a989248 If you merge/rebase master your PR should be OK.

As for phpstan I think you don't need to update the types in the phpdoc, try this and see if it works:

string|array|DefinitionSource

Finally! dockblock syntax on variadic arguments does not seam to be well documented
