Replacing make with mage as a task runner

[devguyio]

I've been a big fan of using mage instead of mage specially for go code due to

• Instead of the tons of shell scripts that Make typically enforces you to do, you write clean, testable, statically typed automation code.
• You can easily use any test packages that were developed for tests directly in the mage file.
• Mage also a couple of helper libraries that make executing shell commands from Go code very easy.
• Many communities are starting to adopt it like Hugo and Kubernetes SIG Release

Here's a mage file that I created for my toy project https://github.com/kcore-io/kcore/blob/main/magefile.go

I also used the nice lipgloss package to end up with some output like this as I believe in having a clear and observable developer experience to reduce human errors.
