[gh actions] introduce "inclusive heat sensor"

Context: https://github.com/jonathanpeppers/inclusive-heat-sensor

This is a new GitHub action that will run for each pull request
description, issue, or comment with the idea it could take action if:

* "Anger" is detected
* "Offensive" text is detected

Down the road, if it is working, we could do things like:

* Add a "spicy" label to the issue

* Auto-hide comments as abuse (or spam?)

For now, we just want to let it run (and do nothing) to see what kind
of comments it flags. This is a test to see if it is useful.

NOTE: I may close/reopen this pull request a few times to run the
action.
