[BUG] enums function doesn't work @Default decorator
<!--

/!\ IMPORTANT: Before opening issue

- Please update all of your packages. I won't investigate on the issue if you are on an old version.
- Please check that you have the same version for all Ts.ED dependencies (expected the logger). Many issues are related to a misconfigured packages.
- Please provide a reproducible example (avoid screenshot, prefer copy/pasted code). The stack trace isn't enough to investigate.

If theses requirements aren't checked, I WON'T INVESTIGATE (excepted if you are a PREMIUM SPONSORS!) and issue will be CLOSED!

## Information

- **Version:** 7.29.1
- Packages: @tsed/schema

When using the `enums` function on a typescript enum that is used on a query parameter with the `@Default` decorator, the `"default"` property doesn't get added to the JSON schema.

## Example

```ts
enum Scope {
    PUBLIC = 'public',
    ADMIN = 'admin',
}

// argument for a controller:
@QueryParams('scope')
@Default(Scope.PUBLIC)
@Enum(Scope)
scope: Scope = Scope.PUBLIC,
```

The above code will create a schema like this (Note the "default" property):

```json
          {
            "in": "query",
            "name": "scope",
            "required": false,
            "schema": {
              "type": "string",
              "enum": [
                "public",
                "admin"
              ],
              "default": "public"
            }
          },
```

However, when adding
```
enums(Scope).label('Scope');
``` 
... the default property disappears from the schema:

```json
          {
            "in": "query",
            "name": "scope",
            "required": false,
            "style": "deepObject",
            "schema": {
              "$ref": "#/components/schemas/Scope"
            }
          },
```
```json
      "Scope": {
        "type": "string",
        "enum": [
          "public",
          "admin"
        ]
      },
```

I understand that this would be difficult to get to work from TS.EDs side since the "default" property would sit on the Scope schema in the OAS file. Would it be possible to somehow set a default on the shared Scope enum?
