Update Front-end development article

[magicznyleszek]

Some things that definitely need to be changed:

• Code style section:
  • Update point about JSDoc: it should say we try to use JSDoc-like comments for TypeScript, as it's being used by IDEs
  • Fix all the links for prettier, stylelint, and eslint (and fix others to point to main branch). Most possibly some of these should point to kobo-common project
  • Remove point about BEM, write one about CSS Modules. Add note about dropping bem?
  • Add whole subsection about configuring and using linters in vim, Sublime Text, VS Code, and terminal
• Files architecture section:
  • Add point about functional components preference
  • Add point about filename suffixes (.module, .component, .utils)?
  • remove "don’t use relative paths in imports"
• Icons section:
  • point to Replace webfonts-generator with something better kpi#4109 instead of kpi#3305
• Typescript migration section:
  • rewrite point about dataInterface.d.ts, we store store types in dataInterface.ts
  • drop Reflux point
