Restructure Developer page

[sacdallago]

• Move:

  • What it is
  • How it started
  • Dividing teams
  • Open source & open data project

  sections to about page

• In the API links put a centered div or p tag with the full api link spelled out, like: https://api.got.show

• Create a table also for the GitHub repos, as for the NPM packages, linking to the repos on the Rostlab organization (we are not gonna move the repos in the near future, too many other things to worry about)
