Replace Makefile with earthly

[linuxluigi]

Is your feature request related to a problem? Please describe.

Makefiles are fast hard to read & to maintain. It would be nice to have a more elgant alternative like earthly.

Describe the solution you'd like

Replace current Makefile with an Earthly file. Earthly could also be split up into multiple files & folders. So this could also help to make go-template fit for more options, since not everything needs to be going into one file. Also with earthly, supporting multiple CI provider would be much easier.

Describe alternatives you've considered

Keep the Makefile 😁
