ci: spelling: update and include advice

[jsoref]

Summary of the Pull Request

This updates the spell checker.
Scheduled checks should now function, this means that if someone has a fork and isn't allowing actions to run in their fork, this repository should be able to run a spell check against the PR similar to the way checks would be run otherwise.

This is designed to be merged after #5207

Detailed Description of the Pull Request / Additional comments

Note: due to a bug in a previous version, i'th was treated as an acceptable term. This update fixes that bug which makes the checking stricter. nth is in the dictionary, and thus I've used it instead.

You can see how advice works because I'm conveniently building on top of an unhappy commit. If @DHowett-MSFT / @miniksa / @zadjii-msft have input about how the advice should be worded, we can certainly adjust that here (or you're welcome to tune it later).

Validation Steps Performed

I pushed this commit (and a couple of variants) to my fork. That resulted in jsoref@f2d57bc (the ❌).

This is really great. Thank you.

@j4james would #5211 (comment) have helped?

My goal is to make the feedback as helpful/understandable as possible. If the problem is that the disclosure widget hid too much, I can work on that too (in the interim, the advice text could suggest expanding it).

@j4james would #5211 (comment) have helped?

Yeah, that definitely would have helped. The only thing I might suggest is clarifying that the first point is for names of people. I was a little confused about that, until I read the README in the dictionary directory.

[jsoref]

I basically created a separate thing because it's reasonably distinct from other things.

The microsoft.txt file in my imagination is things like codenames/software/projects that the code might be built on top of. Whereas names is people / external entities.

I also included Firefox in names.txt. It's really up to the team how they want to use the files. Admittedly, the readme explicitly says people. So,...

Someone else can reorganize them if they can think of better organizing criteria. I'm not attached to the scheme, it's just there as a sample so that the project can experiment/grow into using it in the way that best fits their needs.
