URL translation via VSCODE_PROXY_URI drops query parameters #7573

Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: Chrome
• Local OS: MacOS
• Remote OS: Ubuntu
• Remote Architecture: amd64
• code-server --version: 1.102.2

Steps to Reproduce

1. Run code-server with a configured VSCODE_PROXY_URI
2. Attempt to redirect from a local URL to the proxy, where the URL contains a query parameter.
   (Example: http://127.0.0.1:8888/lab?token=2212f0697bfed279e9a6fa898291a0f44f313b3510965815)
3. Observe that code-server will correctly translate the base url to 8888-{my-proxy}/lab, but that the query param token=... is not passed along. Navigating to the correct URL directly (8888-{my-proxy}/lab?token=...) works correctly.

The example I'm using here is based on attempting to launch jupyterlab via a terminal in code-server,
but this bug is not specific to jupyterlab, the problem presents itself for any URL that contains a query parameter part.

Expected

The query parameters are copied over to the proxied URL, and translation works seamlessly.

Actual

The query parameters are dropped from the proxied URL, and need to be manually supplied in order to provide the correct data to the server.

Are you accessing code-server over a secure context?

• I am using a secure context.

Notes

I suspect that this part of the proxy_uri patch does not function correctly, but I know too little of the workings of vscode to be sure.
