[ruby/prism] Fix parsing rescued exception via indexed assignment
Given this code
```ruby
begin
raise '42'
rescue => A[]
end
```
Prism fails with this backtrace
```
Error: test_unparser/corpus/literal/rescue.txt(Prism::ParserTest): NoMethodError: undefined method `arguments' for nil
prism/lib/prism/translation/parser/compiler.rb:1055:in `visit_index_target_node'
prism/lib/prism/node.rb:9636:in `accept'
prism/lib/prism/compiler.rb:30:in `visit'
prism/lib/prism/translation/parser/compiler.rb:218:in `visit_begin_node'
```
Seems like
```diff
- visit_all(node.arguments.arguments),
+ visit_all(node.arguments&.arguments || []),
```
fixes the problem.
