Upstream Issue: https://github.com/backstage/community-plugins/issues/550

Description of problem:

The github-issues plugin (packaged as a dynamic plugin in RHDH) grabs the first github integrations it finds for all components (even ones that don't use those hosts). This prevents this plugin from being properly used when multiple github integration hosts are present.

Prerequisites (if any, like setup, operators/versions):

N/A

Steps to Reproduce

1. Create a github repo with issues and a github app with permissions to view issues on that repository (make it on github.com)
2. Install the github issues plugin
3. Add at least 2 different github hosts in the github integrations (put the github.com host as the 2nd integration in the list)

integrations: 
  github: 
    - host: github.company.com
      apiBaseUrl: https://github.company.com/api/v3
    - host: github.com
      apps: 

4. Ingest a component with a github slug pointing to the newly created github repo
5. Navigate to the tab containing the issues component
6. Observe error as it tries to query the github.company.com host instead of the expected github.com host

Actual results:

Grabs the very first github integration it finds, uses it and causes the issue fetch to fail. This prevents the use of this plugin when multiple github integrations for different github instances are configured. Only the first github instance would be queried from for all components using this plugin

Expected results:

It should grab the github integration corresponding to the correct host of the component with the github slug annotation. Perhaps a more verbose annotation indicating the host of the github instance can help with this?

Reproducibility (Always/Intermittent/Only Once):

Always
