Read configuration outputs logs as well as configuration

[Explosion-Scratch]

When running devcontainer read-configuration --include-merged-configuration --log-format json --workspace-folder ../workspace 2>/dev/null > server/configuration.json as suggested in the example usage folder, it outputs logs in json format, then at the end, the JSON configuration. Similarly if I remove --log-format json .

Example output:

The logs should be on stderr. 2>/dev/null should hide them. Does this not work?
