fix: support resuming completed deployments

[shetzel]

What does this PR do?

A completed deployment can now be resumed. Also removes the poll function since SDR's pollStatus should be used instead.

What issues does this PR fix or reference?

QA:
sf project deploy resume should display the deploy results from already completed deployments rather than throwing an error.

I added the info about --wait, because I think it's important.

I added a new paragraph about --target-org in the report command, because I thought it was useful information. I think I got it right, but please correct if not!
