### Plurals and paste tenses
In the past, plurals `foo`+`s` and past tenses `foo`+`ed` were
automatically tolerated. This turned out to be a bad design choice on my
part.
The basic example is that `potatos` would sometimes be treated as a
mistake and sometimes not (depending on the presence of `potato`).
You can see in this PR, that this logic resulted in `Applys` being
accepted as a word along with `AppContainered` -- there's nothing
intrinsically wrong w/ the latter, but unfortunately in order to screen
out the former, my shortcut just couldn't stick around. This means that
the `dictionary`/`expect` files will grow perhaps by a tiny bit, but as
you can see, not really by much.
This is also why `thereses` (a user) was accepted as a word in the past
(therese is in the base dictionary, so `therese` + `s` was acceptable).
### Pull requests
When GitHub initially introduced GitHub Actions, the event for
`pull_request` was created without enough permission for a tool like
this to work properly. I worked around that by using the `schedule`
event. In 2020, they introduced a replacement event
`pull_request_target` which has enough permission. This means that I can
stop relying on the `schedule` event.
### Miscellaneous
* I've folded together some `expect/` files since now is as good a time
as any.
* I've included a hint about `excludes.txt` (I added a similar one for
our primary repo recently, and it came up this week in
`microsoft/terminal` -- @zadjii-msft)
* I've standardized on a default of `.github/actions/spelling` to make
the out of the box experience easier for new adopters, so I'm applying
that change here -- if you're attached to the old directory name,
specifying it is still supported. -- note the directory rename may
cause a merge conflict for people with open PRs and changes to the
contents, this shouldn't be a big problem.
This commit introduces a github action to check our spelling and fixes
the following misspelled words so that we come up green.
It also renames TfEditSes to TfEditSession, because Ses is not a word.
