Gracefully handle bad dependency scanner input

We saw that in
https://gitlab.com/gitlab-com/gl-infra/production/-/issues/6051 there
was one CI artifact that had a `dependency_files` input but a `null`
`dependencies`. We now do stronger type checking to ensure the field is
an array.

Relates to https://gitlab.com/gitlab-org/gitlab/-/issues/346971
