Fix issue count error

[tzing0013]

To get the total number of records by setting per page 1. But the GitHub v3 API is returning ONLY the "next" page (&page=2), so LastPage will be zero since rel="last" is not returned from the API call. That make the issue count zero all the time.

Get issue count with GitHub Search API

Thanks for the contribution!

I need to take a look to understand how the switch to the search API changes things.

This change is okay for one-off runs of Criticality Score, but when running it in a batch job we will quickly chew through search query quota, which is separate to REST quota in general.

I really didn't consider the quota. For REST, the only way I know is the loop in next page, so I change it to search API. Is there any other better way for the count, it's honor to learn it.

May get the count with GraphQL API, The lib go-github recommends the library shurcooL/githubv4 for GraphQL.
