A plain Kirby 3 starterkit on steroids!
Mostly just updates for npm packages and the Kirby core in composer. Also add css minification in production/build.
Updated required versions of PHP > 7.3 and Kirby Core > 3.3. This seems to bugfix the [images problem] (https://github.com/FNGR2911/murby/issues/3).
Also updated all npm dependencies for security reasons.
