Use annotation from the model to create OpenApiInfo

The OASIS OData to OpenApi v3.0 says:

4.2.1 Field title
The value of title is the value of the unqualified annotation Core.Description (see [OData-VocCore]) of the main schema or the entity container of the OData service.
If no Core.Description is present, a default title has to be provided as this is a required OpenAPI field.
4.2.2 Field version
The value of version is the value of the annotation Core.SchemaVersion (see [OData-VocCore]) of the main schema.
If no Core.SchemaVersion is present, a default version has to be provided as this is a required OpenAPI field.
4.2.3 Field description
The value of description is the value of the annotation Core.LongDescription (see [OData-VocCore]) of the main schema or the entity container.
While this field is optional, it prominently appears in OpenAPI exploration tools, so a default description should be provided if no Core.LongDescription annotation is present.

However, the ODL doesn't support "Core.Description" on main schema and Core.SchemaVersion. Once it supports, please update using the annotation.

先檢查主要 schema 對 Core.Description 和 Core.SchemaVersion 的 ODL 支援，然後檢視目前的 OpenApiInfo 產生流程。支援這些註解後，使用它們設定標題、版本和描述；如果沒有註解，則保留預設值。
