Add more metrics for GitHub Action workflows

[HoangNguyen211]

Hi there, can you add metrics to get information of all action workflows of each repo?

is there any priority for this FR ?

As I understood from dependency github-datasource use, it was build for graphQL approach first, but GitHub Action API has no GraphQL implementation yet, and it does not looks as priority also. So the whole question "when" is passing from this plugin to githubv4 solution, which will redirect you to the github developers team. Or .. or we need to develop substitution for the REST solution, which quite challenging, as I understood.
