[Bug] Can't run dbt deps in an offline environment

[alangner]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

We need to run some dbt commands on a machine without internet connection (but with access to a private git repository).
We have dependencies defined in packages.yml that either point to the git repository, or can be provided locally.
In this case we don't need to download dependencies from hub.dbt.com

If we run dbt deps it fails because it cannot contact hub.dbt.com.
This happens no matter if we only define "local" or only "git" ressources in packages.yml

Expected Behavior

If there are no dependencies defined from hub.dbt.com in the packages.yml file, then there should be no call to that URL.
In particular a timeout for this call should not block the dependencies to load.

Steps To Reproduce

1. Define a e.g. local package in packages.yml
   packages:

• local: path/to/package

2. Disconnect from internet
3. Run dbt deps
4. After a long wait time the command will fail
