why did some of these set to true and some set to false?

why did some of these set to true and some set to false?

When the includeAll was set to false for the github_runner variable, when the user first enters the dashboard, it will pre-select a github_runner in the variable. This may not be a very good UX experience, as the GitHub runner name is hidden from the general user.

In this pull request, I change the includeAll of github_runner to true and github_run_id and github_run_attempt to false, so that when the user first enters the dashboard, it will pre-select a github_run_id, which is more intuitive to users.
