[feature request] default content-type value

[lovasoa]

It would be nice if the content-type were not mandatory, using application/octet-stream as a default value. This is the content-type to use for data of an unknown/unspecified type.

Why not be even better and detect content type? That's how csexton/release-asset-action works.

Possible dup of #7.

I'd use application/octet-stream, it is a safe default to push a file 1:1 binary wise. Avoids complexity and should work for everyone.
