define _DEPRECATION_MESSAGE
⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️
NOTE: docker-compose based make commands will be deprecated on (or around) October 1, 2023, in favour of
tilt/k8s based commands. Please familirize yourself with the tilt/k8s commands.

See https://github.com/grafana/oncall/tree/dev/dev for instructions on how to use tilt helm/k8s commands.
