Projects GET endpoint

[hunxjunedo]

can you make quick work of adding a new GET endpoint to the gallery API? It’ll be under a new /projects route, specifically /projects/{project_name}. The project name will be one of gallery-api or gallery-website. This should return JSON data containing information about the project e.g. a list of contributors (and anything else relevant). We don’t need to use a token for this, as the github endpoints for this is publicly available. That said, without tokens, there are lower rate limits and thus, we should cache project information on the gallery API project for up to 1 hour. This ensures we will never hit the github rate limit.
