Ruby image nvm cannot install node 20

Hello!

I'm using the following Dockerfile:

```dockerfile
ARG RUBY_VERSION=3.3
ARG DISTRO_NAME=bullseye
FROM mcr.microsoft.com/devcontainers/ruby:1-$RUBY_VERSION-$DISTRO_NAME

ARG NODE_VERSION="20"
RUN su vscode -c "source /usr/local/share/nvm/nvm.sh && nvm install ${NODE_VERSION} 2>&1"
# . . .
```

And when I'm building the image, it crashes with
```
RUN su vscode -c "source /usr/local/share/nvm/nvm.sh && nvm install 20 2>&1":
0.987 Version '20' not found - try `nvm ls-remote` to browse available versions.
------
failed to solve: process "/bin/sh -c su vscode -c \"source /usr/local/share/nvm/nvm.sh && nvm install ${NODE_VERSION} 2>&1\"" did not complete successfully: exit code: 3
```

In the same time, when I'm installing the same node's version locally, not from the Docker, it's done successfully.

Could anybody help me, please?
