fix: add PR `number` for paged pull requests

[hicksjacobp]

We found that when a PR has a large number of reviews, that the processing of the pull request will fail because it finds the PR number to be null (see line 994). This is because the PR number is not included in the request for subsequent pages.

Here's an example output run where we had an issue. You can see number is not requested.

21:26:59  Analyzing Pull Request Reviews for: mui PR: 7745
21:27:00  More pages of reviews. Gathering next batch.
21:27:00  Getting pull request reviews
21:27:00  curl -kw '%{http_code}' -s -X POST -H "authorization: Bearer ****" -H "content-type: application/json"   --data "    {
21:27:00    "query":"{ repository(owner:\"metasys\" name:\"mui\") { owner { login } name pullRequest(number:7745) { commits(first:1){  totalCount   }    timeline(first: 1) {  totalCount    }    comments(first: 1) {  totalCount    }    reviews(first: 100, after: \"Y3Vyc29yOnYyOpO5MjAxOS0wOC0wMlQwOTo1ODoyNC0wNTowMLkyMDE5LTA4LTAyVDA5OjU4OjIzLTA1OjAwzgACvo4=\") { totalCount pageInfo { hasNextPage endCursor } nodes { comments(first: 1) {    totalCount } } } } }}"

... and later
