Preview Deployment not deployed correctly in Pull Request from forked repository

To Reproduce

1. Create application
2. Enable Preview Deployment
3. Create a Pull Request from one of the forked repository
4. Visit /etc/dokploy/applications/{{aplication_name_preview}}/code in host machine
5. Execute git ls-remote --get-url origin

When you follow the steps, in the preview code folder, the remote origin url is not the pull request source repository, but it is the application's repository

Current vs. Expected behavior

Following the steps

Expected Behaviour:
When accessing the preview deployment folder (/dokploy/applications/{{application_name_preview}}/code) on the host machine, the repository should reflect the source repository with the pull request (PR).

Current Behavior:
Instead of being on the pull request source repository, the repository remains on the application's repository. This prevents the preview deployment from accurately reflecting the PR changes.

Will you send a PR to fix it?

Maybe, need help

No files, tests, or entry points are named. Reproduce the forked pull request preview deployment, then trace how the preview repository is configured and verify the resulting code directory's origin; done means it points to the pull request source repository while normal application deployments remain unchanged.
