class and properties with no spaces between them seem to be allowed

[greg0ire]

While working on applying this standard on doctrine/orm, we found with @SenseException that the following will not raise any error:

// declarations
class Foo
{
    /** @var int */
    private $bar;
    /** @var int */
    private $baz;
}
class FooBar
{
}

We would expect errors about the lack of space between property declarations
and class declarations. Does anyone know of a sniff that we could integrate to
doctrine/coding-standard for this? @kukulich maybe?

Note that in PHP 7.4, I personally would be ok with a lack of space between property declarations when they fit on one line.
