cannot use file (type *io.Reader) as type io.Reader in argument to io.Copy

[markns]

Hey @JonasFranzDEV, I get the following compilation error using the latest commit:

# bitbucket.org/gridarrow/gridarrow-manager/vendor/code.gitea.io/sdk/gitea
vendor/code.gitea.io/sdk/gitea/attachment.go:11:2: imported and not used: "io/ioutil"
vendor/code.gitea.io/sdk/gitea/attachment.go:58:21: cannot use file (type *io.Reader) as type io.Reader in argument to io.Copy:
	*io.Reader is pointer to interface, not interface

This is with the following glide dependency:

- package: code.gitea.io/sdk
  subpackages:
  - gitea

Previous commit works fine for me. Not a go expert, so perhaps it's my bad somehow...

I will fix it today
