Importing vocabulary with field shows PHP warnings

[yorkshire-pudding]

Description of the bug

Found on PHP 8.3 but could arise in earlier versions.
I found this while testing the fix for #2237
If importing a taxonomy vocabulary with field(s), it imports but warnings are shown

Steps To Reproduce

To reproduce the behavior:

1. Create a taxonomy vocab with a field
2. Export config
3. Delete the vocab in the UI
4. Run import

Actual behavior

Vocab was successfully imported but warnings:

user@machine:~/projects/bee/backdrop$ lando bee config-import
The following config will be imported:

| Config                                       | Status |
| field.bundle.taxonomy_term.test              | create |
| field.field.field_test                       | create |
| field.instance.taxonomy_term.test.field_test | create |
| taxonomy.vocabulary.test                     | create |

I think part of the issue is this file, which doesn't seem to be populated with name. I wonder if this file is redundant as I don't see comparable files for node types.

field.bundle.taxonomy_term.[vocab_name]

{
    "_config_name": "field.bundle.taxonomy_term.test",
    "bundle": "test",
    "entity_type": "taxonomy_term",
    "view_modes": [],
    "extra_fields": {
        "form": {
            "name": {
                "weight": "-5"
            },
            "description": {
                "weight": "0"
            }
        },
        "display": []
    }
