Tweak to InitialIssueTriage and PullRequestTriage rules

[JimSuplizio]

There are several changes here:

1. The InitialIssueTriage interim rule wasn't initially set to add the customer-reported and question labels. When looking at this @jsquire and I determined that the PullRequestTriage rule also needed to be updated.
2. The Author Feedback Needed and Author Feedback rules, in the README were swapped in which one should add the comment which meant the rules also had to be updated. The README and rules function comments reflect this.
3. The way Actions updated an issue or pull_request had to be changed. The short version is that the IssueUpdate can't really be used for Actions. This was causing things that the user did (updating labels, or changing things like the title and description) while the actions were being processed, to get reverted or, in some cases, completely overwritten. For labels, the IssueUpdate is a complete replace. Adding/Removing labels is now done through Octokit's IssueLabelsClient which is additive when adding labels. The only thing the IssueUpdate is used for, in Actions, is to set the state. Everything else is nulled out to prevent it updating. This fixes: Actions timing: Changes made by the user, while an action was processing and revert those changes #5835
