Publish grads open for work on People channel

## I want to do this:

Develop the graduate entry type on the People channel on the new CYF website https://github.com/CodeYourFuture/cyf-main-website

## Here’s why I want to do it:
- Trainees have built a graduate directory or register a bunch of times, but it always gets lost. An entry type on our website would be more discoverable
- It would be useful for the Employment Programme to have a portfolio of grads they can share with prospective employers
- It would be useful for grads to be represented on our website, which should also be their website
- It would be a good, chunky, impactful piece of UI to build for someone's portfolio

## Here’s how it serves our goals:
- Our trainees represent us, we should represent our trainees

## This is how much time I can put towards this change:
- I can pair with a grad to build this, for up to 6 121 sessions in total

## This is the help I need from others to get this done (if any):
- I need someone to deploy the new website #3

Comienza revisando el nuevo sitio web de CYF enlazado en la issue, centrándote en el canal People y en cómo debería aparecer un tipo de entrada de graduado. Consulta la issue de despliegue #3 antes de planificar el trabajo. Se considera terminado cuando el tipo de entrada del directorio de graduados está implementado y publicado en el canal People.
