Subject: [PATCH] Mark unsafe for `Lint/RaiseException` cop

Follow up https://github.com/rubocop-hq/rubocop/pull/8169#issuecomment-647012793.

`Lint/RaiseException` cop is unsafe due to incompatibility
between bad and good cases.

## bad case

```console
% cat /tmp/example_for_exception.rb
begin
  raise Exception
rescue
  puts 'Handle exception'
end

% ruby example_for_exception.rb
example_for_exception.rb:2:in `<main>': Exception (Exception)
```

## good case

```console
% cat example_for_starndard_error.rb
begin
  raise StandardError
rescue
  puts 'Handle exception'
end

% ruby /tmp/example_for_starndard_error.rb
Handle exception
```
