Fix incorrect result after using RemoveByType in PhpDocInfo

[carlos-granados]

In the new InlineVarDocTagToAssertRector Rector rule we call the function RemoveByType() in the PhpDocInfo class like this:

                    $phpDocInfo->removeByType(VarTagValueNode::class, $variableName);

If we apply this to this example code:

            /**
             * @var Expression $stmt
             * @var FuncCall $expr
             */
            $expr = $stmt->expr;

We will call it with $variableName = "expr"

In the node visitor defined in line 266 of the PhpDocInfo class we would start by processing a node instance of PhpDocTagNode and its value would be an instance of VarTagValueNode so the first check would be true but the check in line 276 would be false because the variable name does not match the one we passed. Previously we would have returned null and the processing would have continued. We would then process the children of this node and one of them would be the VarTagValueNode. Since it matches the type of node that we want to remove it would be removed, but then we would be left with an invalid parent PhpDocTagNode node with value null and this can create issues if another rule tries to process this same node later on.
If the node value is a VarTagValueNode but the variable name does not match, the right solution is to stop processing the children of this node and this is what this PR implements

Hope this makes sense 😅

The Windows job failed but I think this is unrelated to this fix as it just timed out, can you maybe re-run it?

Let's give it a try, thank you @carlos-granados

@carlos-granados btw, could you add test for it, you can place under tests/Issues for multi rules apply? Thank you.
