Fix content size does not match error when uploading lfs file (#29259)
![image](https://github.com/go-gitea/gitea/assets/38434877/cd726b4d-4771-4547-8aee-ae4e4b56b1d1)
When we update an lfs file by API
`api/v1/repos/{owner}/{repo}/contents/{filepath}`, there will show an
error
```json
{
"message": "Put \"05904d6c7b
\": readfrom tcp [::1]:57300->[::1]:9000: content size does not match",
"url": "http://localhost:3000/api/swagger"
}
```
The reason of this error is
https://github.com/go-gitea/gitea/blob/main/services/repository/files/update.go,
in this file, the `file.ContentReader` been used twice. So when use
`file.ContentReader` in the second time, the `i` of this Reader has been
updated to the length of the content. it will return 0 and an `io.EOF`
error when we try to read cotent from this Reader.
