Potential typo in `LegacyITransforamtionOptions` interface name

Couldn't see an issue (open or closed) around this so unsure if it's known or not.

Instead of "Transformation" [this interface is called "Transforamtion"](https://github.com/cloudinary/js-url-gen/blob/8f61b55a7dc81768995cc2312b5a3acef2bc040c/src/types/types.ts#L431C18-L431C47).

If the spelling does get changed, it might still be a good idea to re-export the type as "Transforamtion" and mark it deprecated, otherwise it could break repos that are importing / using the misspelled version.

If leaving as is (or if it's intentional), this issue can show that it's known and not changing I guess.
