Building from requirements in a private repo fails due to permissions

[mpgreg]

When referencing a requirement in a private git repo the buildkit is not able to build despite proper git token caching and commandline access to the git repo.

Dockerfile:

FROM quay.io/astronomer/astro-runtime:7.4.2-base

requirements.txt:
git+https://github.com/astronomer/astro-provider-snowflake.git

astro dev start fails with:

#13 0.394   Cloning https://github.com/astronomer/astro-provider-snowflake.git to /tmp/pip-req-build-d10gal08
#13 0.398   Running command git clone --filter=blob:none --quiet https://github.com/astronomer/astro-provider-snowflake.git /tmp/pip-req-build-d10gal08
#13 0.636   fatal: could not read Username for 'https://github.com': No such device or address

The same code works fine if the repo is public.
