NetBox Importer fails when using custom fields with type multiselect

[lucagubler]

Environment

• Python version: 3.10.12
• Nautobot version: 2.1.9
• nautobot-netbox-importer version: 2.0.0
• NetBox version: 3.6.3

Expected Behavior

Import custom fields with type multi-select into nautobot

Observed Behavior

The importer reports an InvalidChoiceValueIssue and replaces the type with text. All items using that custom field will later fail to be saved.

ImporterIssue(uid='790ec922-b539-56d7-8051-93a828acb98e', name='', issue_type='InvalidChoiceValueIssue', message="{'type': 'Invalid choice value: `multiobject`, replaced with `text`'}")

Steps to Reproduce

1. Create a custom field in netbox with type Multiple selection, e.g. ansible_roles.
2. Add multiple items to that custom field using custom field choices, e.g. ["role_1", "role_2", "role_3"].
3. Use this custom field on an item, e.g. create a new VM and add ansible roles.
4. Try to use the netbox importer.
