Remove attachment APIs from 2025-12-01-preview

- Add 2025-12-01-preview to Versions enum
- Remove addAttachment and deleteAttachment operations from EdgeActions interface
- Delete related example files (EdgeActions_AddAttachment.json and EdgeActions_DeleteAttachment.json)
- Regenerate openapi.json with updated version and without attachment endpoints

These attachment APIs are internal to AFD RP and should not be exposed in the public EdgeActions API.
