Build: Pnpm as package manager and other improvements

[hunshamar]

Background

Pnpm has better monorepo support over npm and improves performance, disk usage, and dependency resolution.

Introduction of pnpm in this project highlighted some issues which are also resolved in this pr.

Solution

• Replace npm with pnpm as package manger
• Update CI pipelines and docker to use pnpm
  • Update docker to install from frozen lockfile, in stead to ensures that dependencies are installed exactly as specified, avoiding unexpected version updates
• Fix dependency cycle where spor-react-icons imports spor-package, which again imports spor-react-icons
• Update docs to use pnpm
• Install correct npm-packages in apps/packages in monorepo. Previously many packages were used from node_modules without being locally installed in project
• Replace package install from npm-feed with direct "workspace*"-installs to improve local development
• Replace inline commands for tsup with tsup.config.ts-files for better readability and maintainability
• Use nodemon to enable hot reload for changes in spor-design-tokens, so you dont need to manually rebuild.

Rått! Før denne merges så er det fint om du tar en gjennomgang av PRen med web-techleads og andre Spor-interesserte. For at vi andre kan lære litt og at vi kan snakke om hvordan dette vil påvirke de andre løsningene vi har. 🙂

Enig!
Snakket litt med Christian og, og vi ble enige om å ta det opp på neste websync-møte.

Mener det er en codesandbox seksjon i denne readme, kan du fjerne den også?
