Stop teaching the old address flags in the docs

The flags are optional now and the page needs no addresses at all, so the examples no longer paste one build's numbers: screenshot.py is shown asking the firmware through tools/uvk5_buffers.py, and the webui example omits them entirely. The paragraph that said they default to one known build is replaced with what actually happens.
