DM-53324: Update ConversionsForFakes cf. new make_injection_pipeline outputs

[leeskelvin]

{Summary of changes. Prefix PR title with JIRA issue.}

---

• Do unit tests pass (scons and/or stack-os-matrix)?
• Did you run ap_verify.py on at least one of the standard datasets?
  For changes to metrics, the print_metricvalues script from lsst.verify will be useful.
• Is the Sphinx documentation up-to-date?

Lee, I see the changes, they look good to me. I agree, this is what RFC-1171 is about.

On AP we will need to start tagging collections with fakes and making sure this is not mixed. That's all. Approved.
