feat(compose): introduce hybrid mode

[jschmid1]

This patch does a couple of things:

• Add dynamic support for docker compose and docker-compose in the Makefile
• add Makefile targets for all Kong Gateway modes
• aliased "make kong-postgres" -> "make kong-traditional" to reflect official naming scheme
• Restructure the README so that "make" commands are prioritized
  • to shorten commands and hide "docker-compose vs docker compose" ambiguitiies

And the original intention:

• Added support for Kong Gateway's hybrid deployment mode.
