Feature - Support for organizations

[jangerhard]

Describe the solution you'd like
Support for organizations and not just users. Requires a different GraphQL call, but it is doable.
Requires a different prop when using the component, and therefore we risk that neither name nor organization is added, so adequate testing is needed.

Additional context

It should be very similar to existing call, except user is switched out with organization.

query someQuery($org: String!, $numRepositories: Int!, $numCommits: Int!) {
  organization(login:  $org){
    repositories(first: $numRepositories, orderBy: {field: UPDATED_AT, direction: DESC}) {
      ...
