fix: remove format extension for public-id

[chunksnbits]

Resolves

Issue #22, i.e. publicId getting malformed in case it contains "."-char other than as part of extension

Technical note

I removed it completely because I think it is not taking effect anyways, due to the explicit "f_[format]" transformation that is applied later on (https://github.com/mayashavin/cloudinary-api/blob/main/packages/url/lib/url.ts#L127)

E.g., If I take the url from the sample

• https://res.cloudinary.com/adacmkv/image/upload/f_auto,q_auto/v1608641937/ADAC%20Klassik/2021/Events/AEC/RS134993_RS129423_8.1_v7gpvg.jpg

even with auto-format (aka f_auto) this will result in content-type image/web_p being downloaded in most modern browsers, despite the .jpg extension that is part of the publicID.

From my understanding the file-extension is only taken under consideration if there is no format-option present, wich will never be the case here?
