chore: expands make usage with the more commonly used targets

[johncowen]

Back in https://github.com/kumahq/kuma-gui/pull/2457 we added a very minimal Makefile based on kuma's and we plan on using this going forwards to give us a thin layer/abstraction over our various utility commands scripts.

This PR adds the minimal/commonly used targets so we can get used to using make as early as possible:

• installing (make install)
• running a dev server (make run)
• testing (make test/unit and make test/e2e)
• linting (make lint)

I've combined installing with running the dev server as installing it now super quick compared to yarn, but I'm not totally sure whether we would inadvertently update the lock file every so often with that. We'll see as we move forwards.

I've added some extra help to get started by way of basic node version checking and "escape hatch" type run/% which calls the corresponding package script so we don't have to have a make equivalent for every single package script, only the common ones. make help should be enough for folks to figure out how to get started.

I've continued to use include files given that we will have to inject different functionality depending on the environment. Idea being you will just need to use make install wherever you are and things should "Just Work(tm)"

Lastly, I updated our DEVELOPER.md to match and cleaned up our package scripts slightly and removed the scripts we don't no longer need.
