bug: Fix PHPDoc alignment fixer containing callbacks using \Closure

[cs278]

Fixes the PHPDoc alignment fixer so that @param annotations using \Closure don't break the alignment, e.g.:

--- a/tests/integration/Sentry/AbstractSentryTest.php
+++ b/tests/integration/Sentry/AbstractSentryTest.php
@@ -71,7 +71,7 @@ final protected function tearDown(): void
      *
-     * @param array<string,mixed>         $input
+     * @param array<string,mixed> $input
      * @param \Closure(mixed,string):void $callback
      */

Quite a simple change in the end, I've just updated the regexp in TypeExpression to handle the backslash.

Kudos, @cs278 !

[cs278]

@keradus I've just squashed all the fixups, the only change was this: 5c108d2 which should mean CI passes.

thank you @cs278

This has broken the tests.

[kubawerlos]

@GrahamCampbell what tests?

[GrahamCampbell]

I should have been more specific, in that the CI is now failing, though the "tests" are passing.

[keradus]

@GrahamCampbell , I think you would be faster to actually raise a fix than raising an awareness that one see on main repo page anyway ;)
#6759

[kubawerlos]

@GrahamCampbell if you look into these there is no single test failing, just style check.
