az costmanagement export uses old version of Exports API incompatible with Exports created using the latest API version..

### Describe the bug

"az costmanagement export" uses an old API version which is not compatible with Exports that were created with the latest Exports API's (API versions 2025-03-01 and 2023-07-01-preview.). The Azure portal currently uses the latest Export API version (2025-03-01) during creation. Therefore, if you create an Export in the Azure Portal using the GUI; you won't be able to view nor manage that same Export using "az costmanagement export" due to the incompatibility of API versions.

Please find below some examples of this issue:

**az costmanagement export list**

**API version used by command**: 2020-06-01
**Issue description:** Incompatible with Exports created using API versions 2025-03-01 and 2023-07-01-preview. When you run the command, any Export created with API versions 2025-03-01 and 2023-07-01-preview will not show in the response. No error message.

**az costmanagement export show**

**API version used by command:** 2020-06-01
**Issue description:** Incompatible with Exports created using API versions 2025-03-01 and 2023-07-01-preview. When running the command for an Export created with API versions 2025-03-01 and 2023-07-01-preview, the API returns a 404 not found response, even when the Export exists in the given scope.

**az costmanagement export delete**

**API version used by command:** 2020-06-01
**Issue description:** Incompatible with Exports created using API versions 2025-03-01 and 2023-07-01-preview.
