Declare content-type for file uploads to scan storages

[vw-anton]

There are web servers which like to have a valid content-type header defined for requests.
We would therefore expect that file uploads like we do in https://github.com/oss-review-toolkit/ort/blob/main/utils/ort/src/main/kotlin/storage/HttpFileStorage.kt declare the media type of the body. E.g. for ZIP file upload "application/zip".

As a work-around, you could configure / hard-code the content-type as a custom header, I guess.

Agree, that's what we have already implemented as a workaround 👍

I guess the challenge here could be that storages, esp. with #5516, could be shared across users with different storage needs / content-types. So the content-type should not be stored per storage, but per user. Or even be made an argument in the FileStorage interface.

@vw-anton is this still a topic for you?

We have a workaround in place so no urgent need anymore.
