feat: extend twenty orm (#5238)

This PR is a follow up of PR #5153.
This one introduce some changes on how we're querying composite fields.
We can do:

```typescript
export class CompanyService {
  constructor(
    @InjectWorkspaceRepository(CompanyObjectMetadata)
    private readonly companyObjectMetadataRepository: WorkspaceRepository<CompanyObjectMetadata>,
  ) {}

  async companies(): Promise<CompanyObjectMetadata[]> {
    // Old way
    // const companiesFilteredByLinkLabel = await this.companyObjectMetadataRepository.find({
    //   where: { xLinkLabel: 'MyLabel' },
    // });
    // Result will return xLinkLabel property

    // New way
    const companiesFilteredByLinkLabel = await this.companyObjectMetadataRepository.find({
      where: { xLink: { label:  'MyLabel' } },
    });
    // Result will return { xLink: { label: 'MyLabel' } } property instead of  { xLinkLabel: 'MyLabel' }

    return companiesFilteredByLinkLabel;
  }
}
```

Also we can now inject `TwentyORMManage` class to manually create a
repository based on a given `workspaceId` using
`getRepositoryForWorkspace` function that way:

```typescript
export class CompanyService {
  constructor(
    // TwentyORMModule should be initialized
    private readonly twentyORMManager,
  ) {}

  async companies(): Promise<CompanyObjectMetadata[]> {
    const repository = await this.twentyORMManager.getRepositoryForWorkspace(
      '8bb6e872-a71f-4341-82b5-6b56fa81cd77',
      CompanyObjectMetadata,
    );

    const companies = await repository.find();

    return companies;
  }
}
```
