[CT-2506] Accept a list of ProjectDependency in dbtRunner's constructor

[MichelleArk]

When provided a list of ProjectDependencys in dbtRunner's constructor, plumb this through to create a manifest.

Per BLG- May 15 23:
Currently ProjectDependency looks like this:

@dataclass
class ProjectDependency(dbtClassMixin):
    name: str

I think we'll need more information about how that becomes a project to estimate this ticket properly.

Closing in favor of #7736
