[viniciusdc]

After #1360 was introduced, we lost the ability to use the inbuilt terminal from within the VScode extension.

This is the current status of the terminal when we attempt to load it:

and this is the extension manager logs:

So, the problems seem to be from the current installation, see this failed network request from the current vscode on quansight-beta:

Request URL: https://quansight-beta.qhub.dev/stable-30d9c6cd9483b2cc586687151bcbcd635f373630/static/out/vs/workbench/services/extensions/worker/webWorkerExtensionHostIframe.html?&vscodeWebWorkerExtHostId=6647b909-3bd4-4cad-8e7e-3e6ad0d626a4

and a useful one from the previous install:

It seems that the proxy for vscode is not correctly configured right now, the current endpoint being accessed is /stable-30d9c6cd9483b2cc586687151bcbcd635f373630/static/out/vs where it should be /user/vcerutti@quansight.com/vscode/static/out/vs
