[Naming] Fix partial rename in RenameVariableToMatchMethodCallReturnTypeRector with same-named nested arrow param

[TomasVotruba]

Fixes rectorphp/rector#9872

Problem

RenameVariableToMatchMethodCallReturnTypeRector renamed a variable at its assignment but left later usages untouched when a nested arrow function declared a parameter of the same name:

$query = QueryBuilder::for(PartMapping::class)
    ->allowedSorts(fn (Builder $query, bool $descending): Builder => $query->orderBy('part_type'))
    ->defaultSort('part_type');

return $this->apiPaginatedResponse($query->jsonPaginate());

resulted in:

$queryBuilder = QueryBuilder::for(PartMapping::class)
    ->allowedSorts(fn (Builder $query, bool $descending): Builder => $query->orderBy('part_type'))
    ->defaultSort('part_type');

// still $query, now undefined
return $this->apiPaginatedResponse($query->jsonPaginate());

Cause

VariableRenamer::renameVariableInFunctionLike() tracks the innermost $currentFunctionLike while traversing, but that tracker is only updated on enter and never reset on leave (the traverser is enter-only). Once traversal left the arrow function, $currentFunctionLike still pointed at it, so isParamInParentFunction() matched the later $query usage against the arrow function param of the same name and skipped it.

Fix

Ignore the tracked function-like when the variable sits after its body (token position), so params of an already-left arrow function no longer block the rename.
