Add support for private users, not just organizations

[steelbrain]

Feature Request

The APIs that this project uses to install itself currently only work on organizations. It would be nice to be able to use this on accounts instead.

Description

ARC runners (https://github.com/actions/actions-runner-controller) use an installation id parameter to be installable on private users. Would that help here?

Context

This change would allow users to not have to move repositories to organizations just because they want self-hosted CI

Possible Implementation

Could do what ARC runners does

I don't think this is possible @steelbrain since you have to have an organization that you add the runner to.

It's trivial to create an org for yourself.

@jakobjs Its quite possible, I did it myself in fact. ARC (linked above) allows this but it has its own shortcomings (images aren't real VMs so you cant use docker etc), so I really like fireactions over ARC

Edit: While it is trivial to create an org for yourself, you have to figure out billing for it, despite already being on a billed personal plan
