Reset the user auth token

Reset user auth tokens stored in the DB as github has apparently change the format of the tokens at some point.

**Context**:

> We noticed that an application, gitcoin, owned by an organization you are an admin of, gitcoinco, used a token with an outdated format to access the GitHub API on January 27th, 2022 at 16:12 (UTC), with a user-agent header of PyGithub/Python.
>
> In order to provide additional security benefits to all our customers, we recently updated the format of our API authentication tokens. We encourage you to reset any authentication tokens used by this app, as well as tokens used by any other apps you may have, with our reset token API.
>
> Alternatively, you can prompt your users to step through the authorization flow again, as outlined in the docs for either GitHub Apps and OAuth Apps.
