cron job: sync contributor

[SKairinos]

create a cron job to sync contributors data from github. This includes summing up points from closed issues per repo

to get the user's closed issues per repo:
https://docs.github.com/en/rest/issues/issues?apiVersion=2022-11-28#list-repository-issues
to get the estimate per issues:
https://developers.zenhub.com/graphql-api-docs/getting-started/index.html#getting-an-issue
please also follow this conversation

Create the following django command to encapsulate all this functionality: python manage.py sync_contributor {ID}
The cron job should then call this command .
Here's an example of a custom command we created to summarize fixtures

See how we make and call cron jobs.
