machine restart policy on-fail should be on-failure #2844
Description
The --restart flag for fly m run has on-fail as one of the options, but this should really be on-failure like it is in the Machines API and Docker's restart policy. See
flyctl/internal/command/machine/run.go
Line 791 in 51a1b8f
Since this is already in use, I'm not sure if it should be fixed or if we can alias on-fail to on-failure and update the docs.
