refactor!: Rename EditComment to UpdateComment on PullRequestsService, split review comment request bodies, and pass by value (#4493)

BREAKING CHANGE: `PullRequestsService.CreateComment` now takes `CreatePullRequestCommentRequest` by value; `PullRequestsService.EditComment` is now `UpdateComment` and takes `UpdatePullRequestCommentRequest` by value.
