PSA for Docker users

[philosowaffle]

Back in December while making some changes (#358) I accidentally made a breaking change to the docker tags.

If you have been using:

docker pull philosowaffle/peloton-to-garmin:latest

You will now need to switch to:

docker pull philosowaffle/peloton-to-garmin:console-latest

Apologize for the unexpected breaking change, but its been this way for long enough that I plan to leave it as is.
