From issue https://github.com/go-gitea/gitea/issues/27314
When act_runner in `host` mode on Windows. `upload_artifact@v3` actions
use `path.join` to generate `itemPath` params when uploading artifact
chunk. `itemPath` is encoded as `${artifact_name}\${artifact_path}`.
<del>It's twice query escaped from ${artifact_name}/${artifact_path}
that joined by Windows slash \.</del>
**So we need convert Windows slash to linux**.
In https://github.com/go-gitea/gitea/issues/27314, runner shows logs
from `upload_artifact@v3` like with `%255C`:
```
[artifact-cases/test-artifact-cases] | ::error::Unexpected response. Unable to upload chunk to http://192.168.31.230:3000/api/actions_pipeline/_apis/pipelines/workflows/6/artifacts/34d628a422db9367c869d3fb36be81f5/upload?itemPath=more-files%255Css.json
```
But in gitea server at the same time, But shows `%5C`
```

```
I found `%255C` is escaped by
`https://github.com/actions/upload-artifact/blob/main/dist/index.js#L2329`.

current actions artifacts implementation only support single file
artifact. To support multiple files uploading, it needs:
- save each file to each db record with same run-id, same artifact-name
and proper artifact-path
- need change artifact uploading url without artifact-id, multiple files
creates multiple artifact-ids
- support `path` in download-artifact action. artifact should download
to `{path}/{artifact-path}`.
- in repo action view, it provides zip download link in artifacts list
in summary page, no matter this artifact contains single or multiple
files.
