Fix missing signature key error when pulling Docker images with SERVE_DIRECT enabled (#32365)

Browse source 
Fix #28121

I did some tests and found that the `missing signature key` error is
caused by an incorrect `Content-Type` header. Gitea correctly sets the
`Content-Type` header when serving files.

348d1d0f32/routers/api/packages/container/container.go (L712-L717)
However, when `SERVE_DIRECT` is enabled, the `Content-Type` header may
be set to an incorrect value by the storage service. To fix this issue,
we can use query parameters to override response header values.

In this PR, I introduced a new parameter to the `URL` method to support
additional parameters.

```
URL(path, name string, reqParams url.Values) (*url.URL, error)
```

---

Most S3-like services support specifying the content type when storing
objects. However, Gitea always use `application/octet-stream`.
Therefore, I believe we also need to improve the `Save` method to
support storing objects with the correct content type.

(cherry picked from commit 0690cb076bf63f71988a709f62a9c04660b51a4f)

Conflicts:
	- modules/storage/azureblob.go
	  Dropped the change, as we do not support Azure blob storage.
	- modules/storage/helper.go
	  Resolved by adjusting their `discardStorage` to our
	  `DiscardStorage`
	- routers/api/actions/artifacts.go
	  routers/api/actions/artifactsv4.go
	  routers/web/repo/actions/view.go
	  routers/web/repo/download.go
	  Resolved the conflicts by manually adding the new `nil`
	  parameter to the `storage.Attachments.URL()` calls.

	  Originally conflicted due to differences in the if expression
	  above these calls.
