check-spelling: Remove stray field

[jsoref]

This feature isn't ready yet and wasn't meant to be included

Summary of the Pull Request

What is this about:
Remove comment handler (unintentionally included in #11114)

(It's fairly harmless as configured, but the noise is worth removing, the event handler should come back w/ the next release when the code is ready...)

What is include in the PR:
Remove an event handler for a future feature

How does someone test / validate:
Be a non-member of the repository and comment on a PR (or check the repository actions list)

I think. (Oddly this event is failing way less than expected.)
