[3.x]: Import: updating existing form generate a error

[Megafry]

Describe the bug

The Import generates an error if the option updating existing form is selected.

in /var/www/html/vendor/verbb/formie/src/helpers/ImportExportHelper.php:221 Undefined array key "handle"

$existingField = $existingFields[$field['handle']] ?? null;

Fix:

221: $existingField = $existingFields[$field['settings']['handle']] ?? null;
...
232: $existingNestedField = $existingFields[$field['settings']['handle'] . '_fields'][$nestedField['handle']] ?? null;

After retrying the import with the fix, my form had 2 pages named "Page 1" therefore I could not test with group/repeater fields.

Steps to reproduce

1. Export a form
2. Import the form with the Action "Update existing form"
3. CraftCMS generates an exception

Thanks for fixing the error, the problem with the duplicate pages is still present, can you also have a look at this?
