Support using @folkehelseinstituttet/style with package manager of choice and/or monorepo

[yleaxeman]

Problem

When using @folkehelseinstituttet/style with Yarn in a monorepo (confirmed) the import references in SASS files to ./node_modules fails.

Solution

Make import statements to root of package, eg. @import 'bootstrap/...'
