Before this change the help for convmv was generated by running the examples each time rclone started up. Unfortunately this involved running the echo command which did not work on Windows. This pre-generates the help into `transform.md` and embeds it. It can be re-generated with `go generate` which is a better solution. See: https://forum.rclone.org/t/invoke-of-1-70-0-complains-of-echo-not-found/51618
