[REQUEST] Fetch organizations from the github user

[arielj]

Before we start...:

• [x] I checked the documentation and didn't find this feature
• [x] I checked to make sure that this feature has not already been requested

Branch/Commit:

Main branch.

Describe the feature:

As a User I want to see my GitHub PRs and issues from any organization

Problem:

Currently, we only fetch issues and pull requests from the organizations defined in an environment variable, so PRs made for projects outside those organizations are not tracked.

Considerations:

We may need to also support configuring which organizations/projects to fetch. I may want to only use dash to track some of them and not track less relevant organizations/projects.

We need to discuss this feature more to find possible problems and caveats before implementing.

I will abide by the code of conduct
