Description

When I try to build a Dockerfile with an ADD instruction pointing to a public Git repository using this action, I get the error fatal: could not read Username for 'https://gitlab.com/': terminal prompts disabled.

Expected behaviour

The action should properly be able to build the Dockerfile by executing the ADD command.

Actual behaviour

The action errors out with fatal: could not read Username for 'https://gitlab.com/': terminal prompts disabled.
