chore: Makefile updates

[kamilprz]

Description

This PR attempts to clean some things up and make developer life smoother.

Adds artifacts to .gitignore to avoid 5k+ files being added after running make quick-build - screenshot below.

Tidies up the Makefile by dividing it into sections, and update comment descriptions to properly appear when running make help.

Adds the following Makefile targets:

• docs-prod-serve: ## Serve a production build of the docs on localhost:3000
• retina-cli: ## Build the Retina CLI
• pretty: ## Run gofumpt, vet and lint
  • I created this as a "one stop shop" that I can run before committing code to make sure that its formatted as the tools expect and doesn't break linting issues. In order to always execute all three tools, I explicitly ignore errors here.

n/a - this was adhoc work, I didn't create an issue for it

Seems I might have screwed up some targets in the process - couple checks failed, will look into it
