DAST fails when using only DAST_WEBSITE

Summary

DAST should support DAST_WEBSITE var instead of the -t [url], but fails when using it.

Steps to reproduce

docker run \
  --interactive --tty --rm \
  --volume "$PWD":/output \
  -w /output \
  -e DAST_WEBSITE=http://example.com
  registry.gitlab.com/gitlab-org/security-products/dast:${VERSION:-latest} /analyze

Example Project

N/A

What is the current bug behavior?

will fail with:

Waiting for https://dev.gitlab.org/ to be available...

ZAP Baseline Scan started
Usage: zap-baseline.py -t <target> [options]
    -t target         target URL including the protocol, eg https://www.example.com
Options:
    -h                print this help message
[...]

What is the expected correct behavior?

Should scan http://example.com

Possible fixes

This is because of https://gitlab.com/gitlab-org/security-products/dast/blob/8edc7a8203638948fd1aacca28b2809ffd45bd76/analyze#L49 zap-baseline always expects a -t parameter.
