wrong CWD in Dev Containers (extensionKind = "ui")

Check the following:

• I have tried setting vscode-neovim.neovimClean in VSCode settings and restarting VSCode.
• I have read the vscode-neovim docs.
• I have searched existing (closed!) issues.

Neovim version (nvim -v)

v0.10.1

Operating system/version

Mac 14.4.1

Problem (including log messages)

On a fresh setup with a Dev Container Neovim sets the CWD to /. This prevents e.g. tab path completion working when opening new files.

Steps To Reproduce

1. Open a project with Neovim and Dev Container Extensions
2. : followed by lua print(vim.fn.getcwd())
3. Output is /

Expected Behavior

I expect the reported working directory to be the root of the project I am working in.
