Fix organization field being null in POST /orgs/{orgid}/teams (go-gitea#27150)

Similarly to the fix in go-gitea#24694,
this addresses the team creation not returning the organization
information in the response.

This fix is connected to the
[issue](https://gitea.com/gitea/terraform-provider-gitea/issues/27)
discovered in the terraform provider.
Moreover, the
[documentation](https://docs.gitea.com/api/1.20/#tag/organization/operation/orgCreateTeam)
suggests that the response body should include the `organization` field
(currently being `null`).
