This PR adds validation for the `--object-format` flag in the `repo create` command. The flag now accepts only `sha1` or `sha256` as valid values, and returns an error for any other value.
Changes:
- Added validation in `runRepoCreate` to check for valid object format values
- Added unit tests to verify the validation logic
- Fixed the field name from `ObjectFormat` to `ObjectFormatName` to match the SDK
The changes ensure that users get clear error messages when using invalid object format values, improving the user experience.
