I have recently released 0.20.0 of the spellcheck GitHub action, I can see that you are using 0.17.0, so an update could be useful to you. Let me know if you have any issues with the proposal and I will try to accommodate.
I can recommend Dependabot for keeping your GitHub actions up to date, if you want a PR proposing a basic configuration, please let me know.
