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

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.

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.
