Swap template data sources

Swap the data sources used by a workbook template. You can swap from one connection to another, and/or from one dataset to another. ### Usage notes - Retrieve the **templateId** by calling the [/v2/templates](https://help.sigmacomputing.com/reference/list-templates) endpoint. - Retrieve the **connectionId** to use as the **toId** by calling the [/v2/connections](https://help.sigmacomputing.com/reference/list-connections) endpoint. - To map the sources of a specific element, you can use the table or dataset ID: - Retrieve the **fromId** for a specific data element by calling the [/v2/workbooks/{workbookId}/lineage/elements/{elementId}](https://help.sigmacomputing.com/reference/list-lineage) endpoint and using the `source` key from the response, which looks like `inode-2PBoXx3UabchxF1F3l07kE`. The ID is everything after `inode-`. - Retrieve table and dataset IDs by calling the [/v2/files](https://help.sigmacomputing.com/reference/list-files) endpoint. Use the `typeFilters` option to filter for table and dataset files. Use `id` field in the response as the `fromId` or `toId`, as relevant.
