`poetry install` authentication issue with http-basic private index (in devcontainer)

Description

Using poetry install in a context without a keyring backend (in this case a devcontainer), trying to pull packages from a private http-basic secured pypi, causes 401 unauthorized in the install process. poetry lock works, and certain GETs earlier in poetry install succeed as well.

devcontainer.json
dockerfile.txt

Workarounds

PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring poetry install -vvv works

Reproduce the failure using the attached devcontainer.json and dockerfile.txt, with Poetry 1.7.1 or 1.8.1 and the documented private index configuration. Compare the authentication behavior of poetry lock and poetry install, including poetry install -vvv and the null keyring workaround. Done means poetry install authenticates successfully without requiring that workaround.
