https://docs.github.com/en/actions/learn-github-actions/contexts#github-context says:

Property name	Type	Description
github.action_repository	string	For a step executing an action, this is the owner and repository name of the action. For example, actions/checkout.
github.action_ref	string	For a step executing an action, this is the ref of the action being executed. For example, v2.

To accept ✔️ these unrecognized words as correct and remove the previously acknowledged and now absent words, run the following commands

... and examine the curl urls, which I've reproduced following the urls for convenience...

curl -s -S -L 'https://raw.githubusercontent.com/check-spelling/gotosocial/spell-check-with-spelling/apply.pl' |
perl - 'https://github.com/check-spelling/gotosocial/actions/runs/4337164095/attempts/1'

The expected results is that gotosocial/spell-check-with-spelling should not be present in the curl url (instead, it should say check-spelling/prerelease just as the first one does).

Described in another way github.action_repository and github.action_ref are empty (broken) in expressions within the run step script definition of a composite action.

Using it in the env field of a run step will behave correctly.

The change between these commits triggered an actions/runner bug
https://github.com/check-spelling/check-spelling/compare/2bb4ea78df51ab5ded5612c08586e6ed59d1f032..50ca43769650975d2dee92e29fa9cbbe30d0247b#diff-1243c5424efaaa19bd8e813c5e6f6da46316e63761421b3e5f5c8ced9a36e6b6R472

E.g. this would work, otherwise wait for GitHub Support to fix actions/runner.
