test(auth): convert users delete / disable helpers to node-fetch style

something about the http module and the previous style of posting to the
emulator wasn't working, in the same way remote-config realtime template
update cloud function wasn't working even though it looked perfect

node-fetch works great though, so convert the two helpers to that

this may be related to a node v18 switch pending / in testing locally where
http module works for v16 but not v18, but node-fetch works for both
