[core.entity_view_display.node.article.default:third_party_settings.layout_builder.sections.0.third_party_settings.lb_plus] => missing schema

third_party_settings:
    sections:
        third_party_settings:
          lb_plus:
            uuid: 3084b21e-317d-44b3-9d74-5e3d126bdc0c

This is what is being complained about.

Hmm, I feel like you shouldn't need to write schema for third_party_settings 🤔

How can I go about reproducing this error?

This error occurred for me when adding the `layout_builder_restrictions` module and setting default custom layouts defined in my theme.
Exporting config creates the following lines in the relevant `entity_view_display` files such as such as `core.entity_view_display.node.article.default.yml`

Under:
```yaml
third_party_settings:
layout_builder:
```
In `sections`

For example:

```yaml
lb_plus:
uuid:
```

and
```yaml
lb_plus:
default_section:
layout_plugin:
label:
```

Adding definitions for this in `lb_plus.schema.yml` seems to solve the errors, tested both locally and on our CI with the patch from the MR above.

Credit to @gabesullice for figuring out the syntax for the missing schema.

LGTM! Thank you very much zrpnr!
